PURCHASE DESCRIPTION

FOR

NRPC50 50 GHz Power Standard Calibration Kit

1.0 SCOPE:

1.1. General Description of Hardware: The NRPC50 with B1 option 50 GHz Power Standard

Calibration Kit enables the precise measurement of microwave power in the DC to 50 GHz frequency range. These units are extremely rugged, highly accurate, and stable with time and temperature. They will be used as standards for the transfer of calibration factors to 50 GHz RF power sensors. These standards shall come with a verification standard which will be used to verify the transfer standard has not drifted or degraded. Unit shall be a thermoelectric-based device, not thermistor-based or diode-based.

1.2. Types of Workload Supported: These standards will be used to calibrate Rohde & Schwarz 2.4 mm power sensors utilized as part of the FSMR Microwave Measuring Receiver (MMR) system.

1.3. The Air Force Metrology and Calibration Program (AFMETCAL) has a requirement for two

(2) units to establish calibration capability for Rohde & Schwarz 2.4 mm power sensors.

2.0 REQUIREMENTS:

2.1. Brand Name Equipment (2.4 mm Power Standard):

Item No. Manufacturer Part Number Description Quantity 1 Rohde & Schwarz NRPC50 plus

NRPC50-B1 option

2.4 mm Power Standard 2

3.0 WARRANTY & TECHNICAL SUPPORT:

3.1. The default warranty & technical support normally offered by the vendor for this product shall be provided with the unit.

4.0 SOFTWARE/FIRMWARE REQUIREMENTS:

4.1. Special Hardware/Software/Licenses Requirements: Any special equipment, fixtures, tools, standards, etc., required for calibration and not common to a secondary calibration laboratory must be supplied with the NRPC50. Any unique accessories including software required for calibration of this item shall be furnished by the manufacturer. For units that fail calibration and are recommended to be aligned or adjusted, either manually or using an automated alignment/ adjustment software, the special hardware, manual instructions, software, software instructions and software licenses (where required by the manufacturer, and shall be valid for the life of the instrument) needed to perform the alignment/adjustment process shall be included with the NRPC50. A list of peripheral support TMDE equipment required to accomplish the calibration/alignment/adjustments of the unit must be provided with the NRPC50. Any unique accessories including software required for calibration of this item shall be furnished by the manufacturer.

4.2. Self-Test: This system shall have the ability to self-test all measurement ranges and functions and verify them to be in or out of specification. This determination shall be displayed and recorded in memory for future reference and comparison. Self-testing shall require no external standards or devices. Program(s) needed to perform system functional test and operational verification shall be provided by the contractor.

4.3. Software/Firmware Identification: All software/firmware used in conjunction with instrument shall be identified by Name, Version, and Date; to be displayed upon startup or located in an “About” menu in the software/firmware.

4.4. Software/Firmware Warranty: The contractor shall warrant that the software/firmware product meets this purchase description, is free from defects in design and operation, and will perform to stated specifications within this purchase description for the length of the equipment warranty.

4.4.1. The contractor (at no additional cost) shall update or replace the software/firmware product as necessary to correct any deficiencies identified in the software/firmware. Replacement software/firmware shall meet or exceed the requirements in this purchase description, shall not require additional training to operate, and shall be warranted for the remainder of the equipment warranty.

4.4.2. The contractor shall bear transportation costs for all replacement products.

4.4.3. The contractor (at no additional cost) shall provide technical support for normal software/firmware usage, clarification of documentation, and resolution of software/firmware problems. The contractor shall have multiple methods for convenient contact of Technical Support. Contact methods may include but are not limited to on-line or telephone.

4.5. Interchangeability:

4.5.1. Software/firmware shall be updateable by AFMETCAL through communication protocols with Windows-based PC or external drive. Instructions on how to perform the update and any required communication software shall be provided.

4.6. Software Instructions: The software normally offered by the vendor for this product shall be provided with the unit. The delivered software shall perform self-tests of the standard and verification standard. The software shall also perform calibration of the Rohde & Schwarz 2.4 mm power sensors using the NRPC50. The software must have an option to utilize gamma correction during the calibration of test items. Necessary drivers and command codes shall be provided.

4.6.1. Calibration Report: The software must display the results of the self-test and any failures encountered during the test. It must also display results of the calibration of test items.

4.6.2. Operations Files: The software must have the capability to store and retrieve calibration files of test items. The software must have the capability to store and retrieve information for generators, power meters, and the NRPC50 used for calibration.

5.0 MECHANICAL & PHYSICAL REQUIREMENTS:

5.1. Storage/shipping case: A storage/shipping case shall be included. The case shall be lined with a protective material (such as foam).

6.0 OPERATOR’S MANUAL: The operator’s manual normally offered by the vendor for this product shall be provided with the unit.

7.0 ENVIRONMENT, SAFETY, AND OPERATIONAL HEALTH: A combination of the system manual, other documentation, and/or the system itself shall identify potential environment, safety and operational health hazards and how they are mitigated when the design itself cannot mitigate them. This will be accomplished through stating the hazard and accompanying mitigation through the use of safety devices, use of warnings, or use of special operational procedures to counter such hazards.

8.0 TESTING: The item will be inspected and accepted at a destination specified elsewhere in this contract. The item will be checked with test equipment and parameters equal to or better than those required assuring specified performance requirements are met. Test equipment has first echelon certification directly traceable to the International System of Units through the National Institute of Standards and Technology (NIST) or other AFMETCAL approved sources where required. Tests will be performed to ensure the item meets or exceeds all the requirements of this purchase description. Such testing does not relieve the contractor of performing all inspections and quality control checks at the point of fabrication, as necessary, to ensure performance as specified.
