Any mixer-based receiving system requires that the built-in mixers have well-controlled amplitude, phase and group delay responses. The R&S®ZVA-K5 option makes it possible to characterize all four complex S-parameters of a mixer with LO access, including absolute phase and group delay. This measurement uses full two-port calibration, which yields high measurement accuracy.
