PURCHASE DESCRIPTION

FOR

Metrology Grade Oscilloscope

1.0 SCOPE: The Air Force Metrology and Calibration (AFMETCAL) program office requires the procurement of a highly accurate, standardized Oscilloscope to establish a consistent technical baseline across all Precision Measurement Equipment Laboratories (PMELs). Establishing this standard will directly support the authoring of Technical Orders (TOs) by enabling engineers to reference a single, reliable model for equipment requirements. Historically, PMELs have independently procured oscilloscopes categorized as Test, Measurement, and Diagnostic Equipment (TMDE). This decentralized approach has limited AFMETCAL’s visibility into field inventory, complicating TO development and supportability. Standardizing this hardware across both PMEL field units and the AFMETCAL engineering lab will ensure seamless technical alignment, simplify operator training, and guarantee identical bench setups.

2.0 PERFORMANCE REQUIREMENTS:

3.0 FUNCTIONAL REQUIREMENTS: It is important to have a user-friendly interface with automation and manual controls available. Manuals that show the programming language would also be required, in addition to the user manual and the service manual with individual steps on how to perform a full calibration of the oscilloscope and any warranted options it may have.

3.1. Automate or Manual Control: Manual control needs to be available but automation compatibility is mandatory to support the Air Force requirement for standardized, repeatable automated calibration. The instrument shall be fully programmable.

3.2. User Interface: The Metrology Grade Oscilloscope shall be controlled by front screen both manually and automation control should be available.

3.3. Operator Skill: This should be user friendly and require little to no training.

3.4. Connectivity: IEEE-488.2 (GPIB): Native rear-panel standard 24-pin GPIB interface. Ethernet (LAN): 10/100/1000 Base-T Gigabit Ethernet supporting LXI Core specifications. USB Ports: Minimum two (2) USB 3.0 host ports on front/rear panels for data/trace transfer; one (1) USB-TMC device port on rear panel for remote bench programming.

3.5. Calibration Requirements: Performance Verification instructions need to be provided.

3.6. International Standards & Publications: The instrument shall be delivered with an ISO/IEC 17025 accredited Certificate of Calibration directly traceable to the Air Force Primary Standards Laboratory (AFPSL) or the National Institute of Standards and Technology (NIST).

4.0 MECHANICAL & PHYSICAL REQUIREMENTS:

4.1. Display: Minimum 10-inch high-resolution color multi-touch display with physical knobs for primary vertical and horizontal controls.

4.2. Dimensions and Weight: a bench top size oscilloscope is preferred, about 15” x 8” x 6” would fall into the appropriate size, no rack mounted/low profile oscilloscopes as those often require an external monitor to see the waveforms and measurement values.

4.3. Components: Passive Voltage Probe should be supplied with oscilloscope.

4.4. Model and Serial Number Identification: N/A

4.5. Carrying/Shipping Case: none required

4.6. Operating Environment/Storage: The Metrology Grade Oscilloscope should perform to all specifications within the following environment:

4.6.1. Operating Temperature Range: 23°C ± 2°C

4.6.2. Operating Humidity Range: 20% to 70% relative humidity

4.6.3. Storage Temperature Range: -20C to +60C

4.7. Facility Requirements:

4.7.1. Electrical Power and Connections: Universal AC line input operating from 100 to 240 VAC ± 10% 47 to 63 Hz single phase, complying with standard DoD facility power.

5.0 WARRANTY & TECHNICAL SUPPORT: A minimum of a three (3) year warranty for this product shall be provided with the unit. Technical support shall be offered by the vendor for the life of the unit or until such a date that the unit enters obsolescence.

6.0 CONTROLLER REQUIREMENTS: There are no controller requirements.

7.0 SOFTWARE/FIRMWARE REQUIREMENTS:

7.1. 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.

7.2. 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.

7.3. Interchangeability:

7.3.1 When software/firmware upgrade is anticipated by a manufacturer during the life of this contract, the contractor shall contact AFMETCAL for concurrence. If AFMETCAL concurs with the proposed upgrade, all previous units delivered under this contract shall be updated to this upgrade.

7.3.2 All software/firmware provided under this contract shall be at the same version, revision, and revision date at the completion of the contract.

7.3.3 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.

8.0 OPERATOR’S MANUAL: In addition to the operator’s manual, a service manual or the performance verification and a programming manual should be provided that is in a searchable electronic format (PDF).

9.0 INSTALLATION: None

10.0 TRAINING: None

11.0 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.

12.0 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.
