  PSA Series 5 feature tour - Zero Span Demodulation

 AM/FM Demodulation

The analyzer can be placed into zero-span mode in order to  demodulate AM or FM signals.

Audio demodulation

The demodulated audio is sent to a built-in speaker at the base of the instrument.  Volume is fully adjustable and an HF filter can be set to reduce hiss.

Alternatively, the audio can be accessed via a 3.5mm jack socket at the top of the instrument.  This provides up to 30mW into 32 Ohms.  Connecting a jack automatically disconnects the internal speaker.

Waveform demodulation*

With option U02 fitted, the modulating waveform can also be displayed against a timebase settable from 5 us/div to 20 ms/div (1:2:5 sequence).

Markers can be used to provide measurement of depth/deviation against time.

* The Waveform Demodulation function requires option U02.
