W9063A analog demodulation measurement application provides easy-to-use analog modulation testers with one-button measurements for AM, FM, PM and FM Stereo/RDS signals.


The W9063A is discontinued after June 1, 2019. The replacement model is the N9063EM0D X-Series Measurement Application with KeysightCare.

Signal analysis

  • Display modulation metrics, such as AM depth, FM deviation, PM deviation, total harmonic distortion (THD), and signal to noise and distortion ratio (SINAD), FM Stereo (left to right ratio, mono to stereo ratio, 38 kHz pilot frequency and phase error)
  • Analyze analog modulated signals with selection of detectors: Peak+, Peak-, (Pk-Pk)/2 and RMS
  • View RF spectrum, demodulated waveform, AF (modulating signal) spectrum, and demodulation metrics table at the same time with quad view: View MPX, mono, stereo, left and right channel and RDS/RBDS decoding of FM Stereo signal; view transmitter "attack/release" timing
  • Play the modulating signal over a speaker (sometimes referred to as “tune and listen”)


  • Modulation analysis for AM, FM, PM and FM Stereo signals
  • One-button measurements
  • Supplies most complete set of post-demod filters
  • Runs inside CXA signal analyzer


  • AM depth accuracy: ±0.2% + 0.002 × (measured value); AM rate accuracy: ±0.05 Hz
  • FM deviation accuracy: ±0.4% x (rate + deviation); FM rate accuracy: ±(0.01% x reading)
  • PM deviation accuracy: ±(1 rad x (0.005 + (rate/ 1MHz)); PM rate accuracy: ±0.2 Hz
  • FM Stereo SINAD 67 dB and left to right ratio 68 dB with CCITT filter

Other features

  • License key upgradable
  • Fixed and transportable perpetual license available
  • SCPI remote user interface

The analog demoduation measurement application for CXA is one in a common library of more than 25 measurement applications in the Keysight X-Series, an evolutionary approach to signal analysis that spans instrumentation, measurements and software. By expanding the X-Series signal analyzers into easy-to-use analog modulation testers, the application provides fast one-button measurements for AM, FM, PM and FM Stereo/RDS signals. The measurement application further offers a variety of tools to make your analog demodulation faster, easier, and more accurate.
