Rohde & Schwarz will be demonstrating a new technique for measuring the group delay of frequency-converting devices at EuMW 2009. The technique does not require access to the local oscillator (LO) of the device under test. This is extremely useful in applications such as satellite communication links and highly-integrated devices in which the LO cannot be accessed. The solution is extremely fast, easy to use and insensitive against phase and frequency instabilities of the embedded LO. It is available as an option for all four-port R&S ZVA and R&S ZVT Series of vector network analyzers.
