Modulation Analyzer

The new Test and Measurement standard for FM…

AVAILABLE MEASUREMENTS


  • RF spectrum analyzer 87.5-108MHz
  • Multiplex/composite Spectrum analyzer 0-100 kHz
  • Audio spectrum analyzer 0-20 kHz (Left and Right)
  • Modulation analyzer of the composite signal - before stereo decoding- : MPX, Mono, Stereo, pilot 19kHz
  • Modulation analyzer of the decoded audio signal : Left, Right, Left+Right, Left-Right
  • Level of the subcarriers between 55kHz and 95kHz
  • A complete RDS analyzer taking account of all the groups and sequences
  • An oscilloscope allowing a display of the demodulated signal (Lab version)
  • A signal generator allowing internal calibration and also useful for “Zero Bessel” method (75 khz deviation calibration) measurements
  • Distortion meter
