Group delay measurement on devices with an embedded LO using the R&S ZVA vector network analyzer

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.
