Vector And Scalar Mixer / Converter Measurements
S95083B
-
The Keysight S95083B measurement software includes the scalar mixer / converter plus phase (SMC+Phase) measurement class. It provides fully calibrated conversion gain / loss, relative phase, and absolute group delay measurements of mixers and converters without the need for reference or calibration mixers. Eliminating the calibration mixer requires a U9391C / F / G comb generator and an external DC power supply. A vector mixer characterization (VMC) is also included for measuring group delay of frequency-converting devices. VMC can be used to characterize a user-supplied calibration mixer.
