PURCHASE DESCRIPTION

FOR

Microwave Measurement Receiver

20E-102A-RF & 20E-102B-RF

1.1. SCOPE: AFMETCAL is seeking to purchase Microwave Measurement Receivers (MMR) for its Precision Measurement Equipment Laboratories (PMEL’s) and Air Force Primary Standards Laboratory (AFPSL). The MMR shall be used in calibration of Signal Generators and Fixed & Variable Attenuators. Nearly all the parameters of a Signal Generator shall be calibrated with the Microwave Measurement Receiver; RF Output Accuracy, Flatness, Spectral Purity (Harmonics, Non-Harmonics, Sub-Harmonics), Analog Modulation (AM, FM & PM).

AFMETCAL is also seeking to purchase two Alignment Systems and/or equipment or accessories required for periodic recertification and adjustment of the MMR.

1.2. HISTORICAL BACKGROUND: This procurement seeks to replace and improve upon the Keysight N5531S Microwave Measuring Receiver which was procured in 2005. This was the first Microwave Measuring Receiver to reside on a Spectrum Analyzer platform, unlike its previous predecessor the Agilent 8902A (procured in the 1980’s).
