R&S®FSL-K7 AM/FM/φM Measurement Demodulator

Key Facts

The R&S®FSL-K7 AM/FM/φM 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
