AFMETCAL, the Air Force Metrology and Calibration Authority, has ordered signal source analyzers (SSA) from Rohde & Schwarz. They will be operated in AFMETCAL’s precision measurement equipment laboratories (PMEL’s) and Air Force primary standards laboratory (AFPSL). The signal source analyzers are used for calibration of phase noise analog (AM, FM & PM) and digital modulation measurements. For phase noise measurement Rohde & Schwarz has also provided cross-correlation offering very high sensitivity, flexibility and fast measurement speed — all in one box.

This application note reviews the fundamentals of residual or additive noise and addresses measurement techniques for determining the amplitude (AM) and phase noise added by two-port devices such as: amplifiers, mixers, block frequency converters, multipliers, dividers, and frequency synthesizers.
