Signal integrity – measuring time domain skew between two lines on a differential transmission (part 4 of 4)

This video demonstrates group delay and relative phase measurements on frequency converting devices where access to the LO is limited. The measurements are made using the R&S®ZVA vector network analyzer equipped with the R&S®ZVA-K9 embedded LO mixer delay measurements option from Rohde & Schwarz. Based on a unique and novel two-tone method, mixers and frequency converters can be characterized in a very simple and convenient way.
