PSA Series 5 hand-held RF spectrum analyzers: 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.
