The Keysight N9937A-355 Analog Demodulation option.

Using FieldFox’s analog demodulation, users maintaining AM/FM radio transmitters can demodulate and characterize AM and FM signals. They can tune to the signal and listen to the audio tones using FieldFox’s built-in speakers or a headphone. They can also display the RF spectrum, the demodulated waveform and AM/FM metrics such as carrier power, modulation rate, and SINAD.

FieldFox analog demodulation has two parts: (1) Tune and listen, and (2) AM/FM metrics. Tune and listen is available with the purchase of the spectrum analyzer option, or with a spectrum analyzer FieldFox. AM/FM metrics becomes available when Option 355 is purchased. AM/FM metrics provides the user with RF spectrum view, demodulated baseband signal waveform, carrier power, frequency deviation, SINAD and more.
