TERMS AND DEFINITIONS

Station License - A license or grant issued by the FCC authorizing use of a frequency or frequency band(s) by nongovernment users on commercially allocated frequencies..

Telecommunications System - a combination of facilities, stations, or circuits intended to perform an information transfer function by the use of the radio spectrum.

Radio Frequency Allocation - to an equipment is defined as the acknowledgement by the Government Agency/MILDEP that development and/or procurement of a particular C-E equipment can be supported for operation on a specific radio frequency or band of radio frequencies within the radio frequency spectrum. By coordinating a completed DD Form 1494 (Application for Equipment Frequency Allocation) through the US Military Communications Electronics Board (USMCEB), and other agencies as necessary, we are ensured that the type of service provided by the equipment matches the National and International Tables of Frequency Allocations, complies with applicable standards, and does not increase chances of electromagnetic interference (EMI) to other C-E equipment operating in the same electromagnetic environment.

Radio Frequency Assignment - Authorization given by an administration for a radio station to use a radio frequency or radio frequency channel, allocated to government use, under specified conditions.

Obtaining Foreign Disclosure Authority - The release of technical information contained in the DD Form 1494 to foreign countries is necessary to coordinate RF systems designed or planned to operate outside the US&P. Before releasing technical information, foreign disclosure approval must be obtained by the developing program manager. Chapter 17 of the Boeing Security Manual for Safeguarding Classified Information provides procedures and guidance for obtaining foreign disclosure authority.

OMB Circular A-11, Para 12.4 (e) (Required Consultations, Communications-Electronics)

(e) Communications-electronics systems - Estimates for the development or procurement of major communications-electronics systems (including all systems employing space satellite techniques) will be submitted only after certification by the National Telecommunications and Information Administration, Department of Commerce, that the radio frequency required for such systems is available.

DoD 5000.2R, Mandatory Procedures for Major Defense Acquisition Programs (MDAPs) and Major Automated Information System (MAIS) Acquisition Programs, Part 4, Para 4.4.7 Program Design, Electromagnetic Environmental Effects (E3) and Spectrum Management Systems and equipment that emit or receive hertzian waves shall comply with OMP Circular A-11 to determine spectrum supportability prior to initiating cost estimates for development or procurement. All DoD components shall obtain spectrum utilization guidance from the Military Communications-Electronics Board (MCEB) in accordance with DoD Directive 4650.1.

DD Form 1494 Instructions 5

ALLOCATION PROCESS

The development of draft DD Forms 1494 should include coordination with the SMC Frequency Management as early in the process as possible. Their knowledge of international, national, and DOD regulations, policies, and procedures can ensure radio frequency bands tentatively selected for development and testing consider other occupants of the desired radio frequency band(s).

Normally, radio frequency bands selected are from those allocated in International or National Tables to the radio service appropriate for the equipment/system being developed. Submission of applications, which request allocations for frequency bands not currently allocated for that type of system, may only delay application processing. Additionally, other systems currently allocated in the same radio frequency band(s) that may cause EMI problems.

After giving due regard to protection required and possible operational restrictions, other radio frequency bands may be proposed. Contractual, operational, technical, and/or economic justifications must be included with the submission.

Once the radio frequency band(s) have been identified, the program organization, with assistance from SMC Frequency Management, prepares a DD Form 1494 for each piece of RF equipment being developed or modified. The SMC Frequency Management will then forward the application to the AFSPC Frequency Management Office (AFSPC CSS/SCIS).

As the application makes its way from the System Program Office (SPO) through MILDEP frequency management channels, it is reviewed and comments, recommendations, and specific directions are provided.

MILDEP frequency management validates the requirement and reviews the application to determine the validity of the requirement, the EMC considerations, and the technical aspects of the application.

Once the technical review is completed satisfactorily, MILDEP frequency management validates the requirement. The allocation is coordinated with other services through membership position on the J/F 12 Working Group of the USMCEB and, when necessary, with the NTIA through membership on the SPS of the IRAC.

Once all requirements are met and coordination is complete, the application will be approved.

The Company will receive notification through the SPO or appropriate frequency management office.

The processing of radio frequency allocation applications is an iterative process. The procurement process contains four stages: conceptual, experimental, developmental, and operational. Once the initial allocation is granted and as the system proceeds through these stages, major changes are likely to occur that will have direct impact on the equipment allocation.

When these changes occur, the program must notify the SMC Frequency Management so that appropriate adjustments can be made.

Depending on the phase of development, the turn-around time for allocation papers ranges from 6 to 18 months. The Equipment Allocation matrix shown on the next two pages should serve as a guide for determining submission requirements and approval lead times.

DD Form 1494 Instructions 8

DD FORM 1494 INSTRUCTIONS

a. The following guidance should be followed when completing a DD Form 1494:

(1) Use the actual tuning range(s) of the equipment.

(2) Include a releaseability statement if the equipment is to be used outside the US&P.

(3) If you have questions concerning the DD Forms 1494, contact Frequency Management, SMC/EAA, (310) 653-1428/1253 OR DSN: 633-1428/1253

b. The completed application should be assembled in a logical manner to facilitate review and preclude confusion. The procedures will be as follows:

(1) The DD Form 1494 is used to coordinate the frequency allocation application both nationally and internationally. It will be assembled in different order depending on the forum to which it is being submitted. This means that the NTIA General Information page will have more than one page number for different submittals and will have its page numbers assigned by the Government Agency/MILDEP when the DD Form 1494 is assembled for submission. The originator should leave the "PAGE" block of this page blank.

(2) Other pages will be numbered as specified below. The DoD General Information page can only be page 1 and is pre-printed "Page 1 of ____ Pages." The originator should insert the total number of pages in the space provided. The correct number to insert is the total number of equipment characteristics pages (transmitter, receiver, and antenna) plus two (for the DoD and NTIA General Information pages) plus the total number of continuation pages, line diagram pages, and space systems data pages. The Foreign Coordination General Information page will also be a page 1. The equipment characteristics pages should be numbered sequentially beginning with the transmitter pages, then the receiver pages, and finally the antenna pages. The first transmitter page is always page 2. Each continuation page should be placed (and numbered accordingly) directly after the page that it continues. For example, a system planned for operation in CONUS and abroad that includes one transmitter, three receivers, and two antennas would have the following pages marked as follows:

Page Numbered

DoD General Information Page 1 of 9 Pages

Transmitter Equipment Characteristics (1) 2

Receiver Equipment Characteristics (3) 3, 4, 5

Antenna Equipment Characteristics (2) 6, 7

Line Diagram 8

NTIA General Information (leave blank)

Foreign Coordination General Information 1

DD Form 1494 Instructions 9

DD Form 1494 Instructions 10

c. The DD Form 1494 is a multi-page form that may be classified. Classification determination and marking shall be in accordance with applicable program classification guides and DoD Directive 5200.1-R.

(1) Frequently, individual pages are classified differently than other pages.

For example, a system might have SECRET data on the transmitter and receiver equipment characteristics pages, CONFIDENTIAL data on the antenna equipment characteristics page but only unclassified data on the other pages. In this case, the overall classification is SECRET and each page is marked with the highest security classification of the data on that page. Each page has a classification block at the top and bottom. The terms "UNCLASSIFIED," "CONFIDENTIAL" or "SECRET" should be typed into those blocks.

(2) If a page is classified either CONFIDENTIAL or SECRET, then every block on that page shall be marked with its appropriate classification based on the data entered in that block. This block-by-block marking should conform with the paragraph marking defined in applicable program classification guides and DoD Directive 5200.1-R.

(3) The overall (highest) classification of the document must be conspicuously stamped on the top and bottom of the first page and top and bottom of the back of the last page. In some cases, the first page will have a classification lower than the overall classification. When this happens, the classification block on top of the first page should contain either "This Page is UNCLASSIFIED" or "This Page is CONFIDENTIAL," as appropriate, in addition to the overall classification stamp.

(4) The application title (Block 1 of the DoD, NTIA, and Foreign Coordination General Information pages) should never be classified.

(5) The terms "Competition Sensitive" or "Proprietary Data" are not classifications and, therefore, should not be entered into the classification block. If the data contained on the form is of this nature, the words "Competition Sensitive" or "Proprietary Data" should be typed on the top and bottom margins of the form and/or stamped in the "Remarks" block. The J/F 12 process is designed to handle and protect proprietary data. Within a reasonable time period, the Competition Sensitive designation must be removed. After contract award, the data on a DD Form 1494 cannot continue to be considered proprietary.

(6) Three pages (DoD General Information, NTIA General Information, and Foreign Coordination General Information) have "Downgrading Instruction" blocks at the bottom.

The downgrading instruction for the presented information must be supplied for classified systems. All downgrading instructions must conform to the requirements of applicable program classification guides and DoD Directive 5200.1-R. For unclassified systems, the entry "NA" is applicable.

d. This DD Form 1494 is the latest form revised by the USMCEB. Each block of the DD Form 1494 is explained on the back of that page with some information for completing the block. More specific instructions for completing the blocks of the DD Form 1494 are included on the following pages. A blank DD Form 1494 appears for reference at the end of these instructions.

PAGE 1 OF THE DD FORM 1494

DoD General Information

The first page of the DD Form 1494 contains general information concerning the nomenclature, use, number of equipments, and radio frequency requirements of the equipment being allocated.

Classification and Downgrading

See Paragraph c. above.

Date

Enter the date of the application.

Page Numbering

See Paragraph b. above.

Block To.

Use the appropriate address for submission of all DD Forms 1494:

Department of the Navy Naval Electromagnetic Spectrum Management Office

CNO (OP-940T)

Washington, DC 20350-2000

Department of the Air Force

AFFMA/SCM

4040 N. Fairfax Dr., Suite 204 Arlington, VA 22203-1613

Department of the Army C-E Services Attn: SFIS-FAC Alexandria, VA 22332-2200

Block From.

This block should have the mailing address of the office originating the DD Form 1494.

This may be the command that is procuring, developing, modifying, or using the equipment. This block should not contain the address of a non-DoD agency or office.

Block 1. Application Title

Enter the government nomenclature of the equipment, or the manufacturer's name and model number, and a short descriptive title.

DD Form 1494 Instructions 12

Block 2. System Nomenclature

The system nomenclature is a title describing the radio frequency (RF) system being allocated. It should be unique to this RF component of the overall platform or weapons system.

If a Joint Electronics Type Designation System (JETDS) nomenclature (AN nomenclature) has been assigned to the RF component being allocated, it should be listed in this block along with the name of the equipment. If a JETDS nomenclature is not assigned, a unique descriptive title must be entered; e.g., "AEGIS SM-2 (BLK I) Data Link." In the case of commercially produced off-the-shelf equipment, the title should include the manufacturer's name and model number, in addition to the descriptive title; e.g., "Conic Model TCM-604B High Density Microwave Relay."

The System Nomenclature blocks on the NTIA General Information and Foreign Coordination General Information pages must be identical to that listed on the DoD General Information page.

If a commercial transmitter and receiver made by different manufacturers are being allocated, the System Nomenclature block should reflect this. "Conic Model TCM-604B Transmitter and Watkins Johnson Model 1638 Receiver" would be a correct entry. The title should not be classified or marked competition sensitive. The manufacturer's name is not required in the case of competition sensitive equipment; it is perfectly acceptable to omit this information. Instead, the identifier "Model A" or "Contractor B" should be substituted. "Nomenclature not yet assigned" is not acceptable. When seeking allocation for a complex system made up of two or more RF subsystems, a separate DD Form 1494 must be submitted for each subsystem. For example, the AN/UPD-7 Surveillance System has two distinct RF components: the AN/APS-94 Radar and the AN/AKT-18 Communications Relay. An application for allocation for the AN/UPD-7 would require one complete form for the AN/APS-94 and one complete form for the AN/AKT-18.

DD Form 1494 Instructions 13

Block 3. Stage of Allocation

Stages of allocation correspond to the stages of life cycle management. The amount and type of data required on the DD Form 1494 varies with the stage of allocation. The requirements for each stage are explained below:

STAGE 1 - "Conceptual." A conceptual allocation is prudent prior to releasing funds for studies or assembling "proof-of-concept" test-beds. Little more than the system purpose, the planned radio frequency range, planned system power, and operating location are required to be completed. It is highly desirable, however, that all other planned or estimated details concerning the equipment be entered on the DD Form 1494. Where information has not been determined, the entry "NAvail" or "Not Available" should be made. "Unknown" or "Unk" should NOT be used.

The Stage 1 system normally does not radiate.

STAGE 2 - "Experimental." An experimental allocation is required prior to the release of funds for building a radiating test model or assignment of a radio frequency for experimental usage. This includes, but is not restricted to, units that will be tested within the laboratory.

Estimated and calculated data can be used where appropriate for nearly all the blocks on the DD Form 1494.

STAGE 3 - "Developmental." Prior to release of funds for engineering development models or assignment of a radio frequency for developmental usage, a stage three allocation must be obtained. All applicable blocks of the DD Form 1494 should be filled in with measured data. Where measured data is not available, calculated data must be used. Any entries of "NAvail" must be accompanied by the reason for the non-availability.

STAGE 4 - "Operational." An operational radio frequency allocation is mandatory prior to release of funds for production units. Measured data for all measurable technical characteristics such as emission bandwidth, harmonic level, spurious level, etc., should be provided when submitting a Stage 4 radio frequency allocation application. All commercial off-the-shelf equipment whose RF characteristics have not been modified, fall into this stage of allocation.

Although the equipment is sometimes being used within experimental or developmental systems, it is operational equipment, by definition, because of its off-the-shelf status (for example, an off-the-shelf telemetry system used during development of a missile).

Block 4. Radio Frequency Requirements

Two items of information must be listed in this block. They are the operational radio frequency band(s) and the emission designators.

a. Frequency(ies): Enter the required radio frequency band(s). For equipment designed to operate only at a single radio frequency, enter this radio frequency. Indicate units;

e.g., kHz, GHz.

b. Emission Designator(s): Refer to NTIA Manual of Regulations and Procedures for Federal Radio Frequency Management, Chapter 9, Para 9.8.2 located on Page 9-16.

DD Form 1494 Instructions 14

Block 5. Target Starting Date for Subsequent Stages

These are the dates when the different life cycle management phases of the equipment are to be entered. A projected date for the start of all future phases should be given in this block.

An "NA" should be entered on the line for all current and accomplished phases. Thus, the DD Form 1494 for a system going from the current Advanced or Engineering Development stage to the Operational or Production stage in November of 1992 will have "NA" for Stages 1, 2, and 3 and "November 1992" for Stage 4.

Occasionally, equipment is developed that is never intended to be introduced into the operational inventory. It may be a proof-of-concept test bed or a one-of-kind piece of laboratory equipment. This is indicated on the DD form 1494 by entering an "NA" for the Stage 4 date and an explanation in Block 13, "Remarks."

Block 6. Extent of Use

Some idea of the amount of time and the occurrence of operation of the equipment should be given. For equipment intended primarily for peacetime use, this should include the number of hours per day and days per week. For weapons systems and wartime-oriented systems, some idea as to the number of hours of operation per mission should be given. Most equipments (wartime systems included) have some use in a training role which should also be listed in this block. A sample entry in this block would read "Peacetime training, testing, and use will include approximately 2 hours per day, 5 days per week of intermittent transmissions. During wartime, system will operate at all times with intermittent one-minute transmissions, approximately 10 per hour." The information requested pertains to eventual Stage 4 operations.

Block 7. Geographical Area For

Enter the locations of all tests or operations of the equipment for each stage of allocation including the current stage. Enter "NA" for all accomplished stages.

For STAGES 1, 2, and 3: Wherever possible, specific sites, identified by geographic location and coordinates should be listed. When a large number of U.S. test sites is anticipated or the final sites have not yet been chosen, it is acceptable to state "various test sites in the US&P." Specific (rather than general) locations should be given whenever possible. All test sites outside the Continental United States (OCONUS) must be identified by base, station, or military unit name and country.

For STAGE 4: The locations of operations should be as specific as possible. For fixed equipment, it should be possible to list the site locations by latitude and longitude. For mobile systems where no specific location can be identified, worldwide may be used as a last resort.

Sea areas, coastal areas, or land areas worldwide are preferable. General rather than specific locations lead to time-consuming questions throughout the review process. Use continuation pages when the physical space on the DD Form 1494 is too small to list all locations and specific sites.

Block 8. Number of Units

This block should contain the total number of units being built, procured, or used at this stage of allocation. If the number of transmitters differs from the number of receivers, each should be identified and listed separately. When there is a one-for-one correspondence of transmitters to receivers, a single figure may be listed.

DD Form 1494 Instructions 15

Block 9. Number of Units Operating Simultaneously in the Same Environment

The environment is defined to be the physical area over which the equipment signal can communicate or interfere. For a fixed microwave radio, this will usually be two units: the transmitting station and the receiving station. There may be only one radar in that radar's coverage area. In the case of a base police radio net, there may be dozens of "handie-talkies" within reception range of each other. The number of systems operating may be a variable, so a normal and a maximum value could also be given. The size of the area should also be stated (usually a radius value). The answer to Block 9 can never be "NA."

Block 10. Other J/F 12 Application Number(s) to be

A system should have four radio frequency allocations during its lifetime, as it transitions from one phase to another. Each allocation will have a distinct J/F 12 number assigned when an application is approved. Since each new allocation supersedes the existing allocation, it is necessary to supersede the existing J/F 12 number. Or, if two systems, each allocated separately, are to be used in conjunction with each other, it is necessary to relate the two J/F 12 numbers. This block is intended for these types of situations.

a. Superseded. This is the box most normally used when requesting a new allocation for an already allocated system. The title describes the action that will be taken by the USMCEB Frequency Panel. This block should not be used to indicate that the system being allocated is replacing an existing system. Somewhere, someone will continue to operate the replaced system until it is phased out of the inventory and it will still need a valid radio frequency allocation. The J/F 12 number to be superseded should be listed on the line to the right of the "Superseded" box.

b. Related. This covers the cases of two separately allocated systems being used in conjunction with each other such as a newly developed earth station and an existing space station. The space station's J/F 12 number should be entered opposite the checked box marked "Related." "Related," as it is used on the DD Form 1494, does not extend to cover different systems performing the same or similar purposes, unless the two systems work together. For example, the TERRACOM TCM-604 and the TCM-608 perform a multichannel microwave relay function and have similar RF characteristics, but it is not generally correct to consider them "Related" unless used in the same installation.

Block 11. Operational Requirement

If this equipment will operate with the same or similar equipment used by other U.S.

Military Services, DoD Components, U.S. Government Agencies, or Allied Nations, mark "Yes," and specify in Block 13, "Remarks," the Services, Agencies, or countries (to include the country's services).

Block 12. Names and Telephone Numbers

The name, and telephone number (both commercial and DSN) of the Program Manager and a Project Engineer are required. This information is necessary to permit contact between the Government Agency/MILDEP frequency management and the Project Office during the processing of the allocation. The "Project Engineer" should be familiar with the RF parameters of the system, with who direct liaison is authorized. In addition to the two required contacts, it is not uncommon to list a point of contact with the civilian contractor, if the equipment is being produced or developed by such a contractor. When the organization and address of the Project Engineer or Manager are different from the application originator, this information should be supplied in the "Remarks" section.

DD Form 1494 Instructions 16

DD Form 1494 Instructions 17

Block 13. Remarks

This block may be used as a continuation of any of the preceding blocks. The continued block or blocks should be identified by their block number. The security classification of any information should be identified next to the block number. Any additional information that clarifies the function or operation of the equipment may be entered in this block.

Transmitter Equipment Characteristics

The second page consists of information related to transmitter characteristics. In a multi-transmitter system, a copy of this page should be submitted for each different transmitter. While the information required is sufficient to provide a general description of the transmitter, it is not sufficient to describe transmitters employing spread-spectrum and other advanced-modulation techniques. The additional information required to adequately describe these transmitters must either be provided in Block 14, "Modulation Techniques and Coding," or Block 24, "Remarks," or on additional pages attached to the DD Form 1494. Should the DD Form 1494 be classified, each block of the page must be marked regarding its specific security classification.

Classification (Top of Page)

See Paragraph c. above.

Page Numbering

See Paragraph b. above.

Block 1. Nomenclature, Manufacturer's Model Number

If a JETDS nomenclature (AN nomenclature) has been assigned to the transmitter, it should be entered in this block. If no JETDS nomenclature has been assigned, a manufacturer's model name or part number should be entered instead. If the transmitter has neither type of identifier, as may occur in a conceptual, experimental research, or exploratory development allocation action, at least the system name followed by the word "transmitter" should be entered.

The entry "None" or "Not Yet Assigned" is not valid in this data block. In a multi-transmitter system a nomenclature describing the purpose of each transmitter would be appropriate on each respective transmitter page. For example, "Motorola FSK Telecommand Transmitter" and "Motorola RPV ASK Telecommand Transmitter."

Block 2. Manufacturer's Name

If the system is being built or designed by a contractor, the contractor's name should be listed here. When a manufacturer's model number or part number is listed in Block 1, then the manufacturer's name must be listed here. In the case where a manufacturer has not been selected, as may occur in a conceptual (Stage 1) system, an entry of "NAvail" is acceptable.

Block 3. Transmitter Installation

Required here is the platform(s) in or on which the transmitter is mounted; whether it is mounted at a fixed site atop a mountain, in an S-120 shelter, in a jeep, aboard a helicopter, etc.

All military vehicles should be identified by their proper military nomenclature. If the system is portable, and not mounted in a vehicle, the user should be identified, e.g., man portable carried by military police or handie-talkie worn by flight deck crew or carried by base police.

DD Form 1494 Instructions 19

Block 4. Transmitter Type

The general modulation type and transmitter purpose should be entered as a two- or three-word description. Examples are: "FM Communications," "Pulse Doppler Radar," "Spread- Spectrum Communication," etc. "Not Available" or "Not Applicable" are not permissible entries.

Block 5. Tuning Range

This should be the lowest-tunable center radio frequency through the highest-tunable center-radio frequency. As a matter of uniform convention, this tuning range should not include the transmitter's emission bandwidth. If the transmitter is normally not tunable (e.g., "Fixed Crystal"), the range of the lowest radio frequency obtainable by crystal substitution or cavity adjustment, through the highest, must be listed. This is true even if only one or several specific crystal radio frequencies are intended for use. At a later date, it may be necessary to shift the tuned radio frequency of the equipment, and by correctly indicating the capabilities of the system, the Navy spectrum manager can assess the ability of the system to operate in light of this shift. If the equipment truly cannot be tuned or in any way adjusted in radio frequency, the center radio frequency of the emission or reception should be listed in this block. An example of a truly fixed radio frequency system is an ATCRBS IFF/SIF interrogator, which would have the entry of " 1030 MHz." The range listed in this block may differ from the range(s) given on page 1, Block 4, "Frequency Requirements," if there is more than one transmitter being used to cover the ranges or if the transmitter is capable of tuning over a greater range than is being requested for this allocation.

Block 6. Method of Tuning

This is another two or three-word descriptor with the format of "method of effecting change" and "device ensuring radio frequency output." Examples are: "Manually Adjusted Klystron Cavity," "Fixed Crystal," "Interchangeable Crystal," "Manually Adjusted Crystal Synthesizer, " etc. Even if no tuning is possible, the second half of the descriptor is valid. Thus, a non-tunable radar would still have an entry appropriate for this block: "Sealed Cavity Magnetron."

Block 7. RF Channeling Capability

For uniformly spaced channels, enter the center radio frequency of the lowest channel, and the increments between consecutive center radio frequencies and the number of channels, e.g., 406 MHz, 100 kHz increments, 20 channels. For continuous tuning, enter the lowest radio frequency and the word "continuous." For others, such as SSB, randomly spaced channels, or cases where channel selection is under software control, enter a detailed description in Block 24, "Remarks." Any constraints for using any of these channels also must be described in Block 24, "Remarks," e.g., degraded channels, internal hardwiring limitations, or lockout capability for radio frequency hopping systems. The title contains the word "RF." This is to qualify that only RF output channeling information is appropriate, not the input channeling description. Thus, multiple-input channels combined through "Time Division Multiplexing (TDM)" or "Frequency Division Multiplexing (FDM)" into one RF channel need not be described in this block.

Multiplexing information should, however, be listed in Block 14, "Modulation Techniques and Coding," or Block 24, "Remarks." RF channeling does not include the net channels created by "Distributed Time Division Multiple Access (DTDMA)", but does include the actual radio frequency band(s) occupied by those nets.

Block 8. Emission Designator(s)

Refer to NTIA Manual of Regulations and Procedures for Federal Radio Frequency Management, Chapter 9, Para 9.8.2 located on Page 9-16.

DD Form 1494 Instructions 20

Block 9. Frequency Tolerance

Radio frequency tolerance is defined as follows:

Radio frequency tolerance = maximum transmitter drift (Hz) center radio frequency (MHz)

It should be expressed in "parts per million (ppm)," rather than actual radio frequencies or a percentage of the center radio frequency. A 1 MHz center radio frequency transmitter that can drift 1 Hz has a radio frequency tolerance of 1 ppm. A 100 MHz transmitter with a drift of 10 Hz has a tolerance of 0.1 ppm. (NOTE: Single sideband radio frequency tolerance may be expressed in Hz.) The stability of a transmitter is a function of many factors. It may depend on transmitter temperature, age, or center-radio frequency selection. The value entered into Block 9 should represent the nominal transmitter conditions. Thus, it should reflect operations at the intended operating temperature, a time sufficiently into the equipment's life cycle to exclude "Break-in" or "Pre-Burn-In" variations, and after an adequate warm-up period. It is not necessary to list these conditions in Block 9.

Block 10. Filter Employed

Any filter employed between the final RF stage and the antenna should be indicated in this block, according to its type. Additional information and filter specifications should be listed in Block 24, "Remarks." An example of this additional information would be the entry, "Block 10: 3-pole LP Butterworth filter with 1.5 dB in-band insertion loss and a minimum of 85 dB attenuation at 25 MHz removed from the tuned radio frequency."

Block 11. Spread Spectrum

If spread spectrum techniques are being employed, check the "YES" box and provide a complete description of how the spreading is achieved in Block 14, "Modulation Techniques and Coding" and Block 24, "Remarks." Spread spectrum is defined by the IEEE as "a modulation technique for multiple access, or for increasing immunity to noise and interference. Spread spectrum systems make use of sequential noise link signal structures, for example, pseudo noise (PN) codes, to spread the normally narrowband information signal over a relatively wide band of radio frequencies. The receiver correlates these signals to retrieve the original information signal." The principal spread spectrum methods are direct sequence, radio frequency hopping, and a hybrid of the two. Some examples of a "Remarks" entry would be "Direct sequence pseudorandom noise is used to spread the bandwidth of the telecommand signal. Signal information rate = 14.6 Kbits/sec and chip rate = 18.5 Mbits/sec" or "Radio frequency hopping is employed using 21 discrete software selected channels within the tuning range. The hop rate is 20 Khops per sec."

DD Form 1494 Instructions 21

Block 12. Emission Bandwidth

This block should contain information regarding the approximate spectral energy distribution of the transmitted signal. The term "emission bandwidth" applies to that transmitter energy appearing at the antenna terminals and includes any significant attenuation contributed by filtering in the output circuit or transmission lines. During conceptual and experimental phases, the waveform envelope may be calculated. For developmental and operational allocations, measured data should be provided. The bandwidths of the signals at points -3, -20, and -60 dB relative to the fundamental signal level are required and should not include the tuning range or carrier movement. Spread spectrum (radio frequency hopping) signals should be measured at one radio frequency only, as it is used instantaneously. The -40 dB bandwidth need only be supplied for pulsed radar systems; an entry of "NA" is acceptable for all other types of systems.

Line 12.e. asks for the occupied bandwidth, which is defined by the DoD as the band within which 99% of the total emitted energy is contained. Under no circumstances can the occupied bandwidth be less than the necessary bandwidth listed in Block 8, "Emission Designator(s)." A complete set of bandwidths must be listed for each different rise, fall, and/or width time listed in Block 18. In addition, a complete set of emission bandwidths must be included for each different emission designator listed in Block 8. For instance, a transmitter may be capable of transmitting both pulse doppler and chirped FM emissions. In this case, two emission designators would be indicated in Block 8, and correspondingly, two emission bandwidths must be listed in Block 12.

Additional sets of bandwidths should be put in Block 24, "Remarks" or on continuation pages.

Block 13. Maximum Bit Rate

This applies only to digital communications systems. It does not mean pulses per second for a radar. Enter the maximum information bit rate for digital equipment in bits per second (bps).

Block 14. Modulation Techniques and Coding

Describe in detail the modulation and coding techniques employed. For complex modulation schemes such as direct sequence spread spectrum, radio frequency hopping, radio frequency agile, etc., enter full details in Block 24, "Remarks." An example of an entry in this block would be "A 13 bit Barker Code is used to "compress" the radar pulses."

Block 15. Maximum Modulation Frequency

This applies only to frequency-modulated or phase modulated systems. It is the point that is 3 dB down on the high side of the modulating signal spectrum after any compensation. In other words, it is the highest input frequency that can be successfully transmitted. In the case of a standard analog voice communications radio, the maximum modulation frequency is designed to be 3 kHz, the highest frequency the human voice normally produces in speech. In the case of a multi-channel, frequency-division multiplexed radio; the maximum modulation frequency is the highest frequency of the highest channel after being multiplexed. This is generally easy to calculate. If the radio multiplexes 10 channels, and uses 3 kHz/channel, the highest modulation frequency is 10 x 3 kHz or 30 kHz. For amplitude- and pulse-modulated systems, the correct entry is "NA."

DD Form 1494 Instructions 22

Block 16. Pre-Emphasis

This is applicable only to analog frequency modulated systems. Pre-emphasis refers to preferential amplification of the higher modulating frequencies. Typically, the amplification is 6 dB per octave. If the exact amount of pre-emphasis is known, it should be entered in the space provided in the right-hand portion of the block. Pre-emphasis is common in commercial, off-the-shelf equipment. It is not generally found in military radios. The "NO" block should be checked for amplitude, digital FM, phase, and pulse-modulated systems.

Block 17. Deviation Ratio

This block applies only to frequency-modulation or phase-modulation equipment. For FM systems, the deviation ratio is the ratio of the maximum amount the one-sided RF emission deviates from the center radio frequency (frequency deviation), to the maximum frequency of the input modulating signal. For FM systems the radio frequency deviation is directly proportional to the amplitude of the modulating signal, since the amount of carrier radio frequency "swing" is tied to the amplitude variance of the modulator. In PM systems, the deviation ratio is tied to both the amplitude of the modulating signal and phase deviation constant of the modulator. The PM deviation ratio is not a function of the frequency of the input modulating signal.

Example: For an FM system a deviation ratio of 1 indicates that a 3 kHz input frequency will cause a peak instantaneous radio frequency carrier deviation of 3 kHz. A deviation ratio of 3 would result in a 9 kHz deviation of the emission when modulated with a 3 kHz signal. The formula for the deviation ratio of FM systems is:

Deviation Ratio = Maximum Deviation from fc Maximum Modulating Frequency

For FSK digital FM systems, the deviation ratio is given as follows:

Deviation Ratio = f2 - f1 fb where: f2 = mark frequency f1 = space frequency fb = bit rate

"NA" should be entered in this block for all amplitude- and pulse-modulated systems.

DD Form 1494 Instructions 23

Block 18. Pulse Characteristics

As the title implies, this is applicable only to pulse-modulated systems. It is not appropriate to enter data concerning short duration FM and AM emission transmitters (e.g., radio frequency hopping) in this block. Information concerning transmission rates of repetitive AM or FM emission should be entered Block 24, "Remarks," or on a continuation sheet.

a. Rate - Pulse rates should be listed for individual pulses. While "pulse pairs" are commonly used in IFF system specifications, it is not correct to list the pulse-pairs repetition rate in this block. Rather, the number of individual pulses per second (reciprocal of minimum pulse interval) is the correct figure. If several different pulse rates are employed by the system, each rate should be listed, rather than just the maximum rate. If the different pulse widths are associated with different pulse rates, then the association should be indicated.

b. Width - The pulse width is that time period during which the voltage to the antenna exceeds 50% of the highest voltage that will be conducted to the antenna. This time period is measured in microseconds. The pulse width of a transmitter cannot exceed one divided by the pulse rate (1/pulse rate). To do so would yield a transmitter duty-cycle of greater than 100%. If several different pulse widths are employed by the system, each pulse width should be listed, rather than just the widest pulse.

c. Rise Time - The pulse rise time is the time duration required for the leading edge of the RF voltage envelope being supplied to the antenna to rise from 10% to 90% of its peak amplitude. The time is measured in microseconds. As can be seen by comparison, there is an overlap between the rise time period and the pulse width period.
