Option 355 is the analog demodulation option for the FieldFox analyzer.

• Characterize AM/FM radio transmitters
• Tune to a signal and listen to the audio tones with the built-in speakers or a headphone
• Measure AM/FM metrics such as carrier power, modulation rate, signal-to-noise and distortion (SINAD) with a full selection of post-demodulation filters

With a radio standard applied, pre-defined frequency bands, channel numbers or uplink / downlink selections can be used instead of manual frequency entry. The pre-defined FieldFox radio standards include bands such as W-CDMA, LTE, and GSM. Alternately, users can create custom standards and import them into FieldFox analyzers.
