Rohde & Schwarz FSL-K7

Analogue demodulation AM/FM/PM
The R&S FSL-K7 AM/FM/fM measurement demodulator turns the R&S FSL or the R&S ZVL (with the R&S ZVL-K1 spectrum analysis option) into an analog modulation analyzer for amplitude-, frequency-, or phase-modulated signals. It measures not only characteristics of the useful modulation, but also parameters such as residual FM or synchronous modulation.

Display and evaluation capabilities:
Modulation signal versus time
Spectrum of modulation signal (FFT)
RF signal power versus time
Spectrum of RF signal (FFT versus max. 18 MHz)
Table with numeric display of
Deviation or modulation depth, +Peak, Peak, Peak/2 and RMS weighted
Modulation frequency
Carrier frequency offset
Carrier power
Total harmonic distortion (THD) and SINAD
