The R&S®FSV-K7 AM/FM/φM measurement demodulator option converts the R&S®FSV or R&S®FSVA into an analog modulation analyzer for amplitude-, frequency- or phase-modulated signals. It measures not only characteristics of the useful modulation, but also factors such as residual FM and synchronous modulation.
