A practical example for a basic Analog Demodulation measurement is provided here. It
demonstrates how operating and measurement errors can be avoided using correct
configuration settings.
The measurement is performed using the following devices:
● An R&S FSW with application firmware R&S FSW-K7: Analog Demodulation
●
A vector signal generator, e.g. R&S SMU
