the audio output. Thus, a displayed signal can be identified acoustically with the help of
the internal loudspeaker or with headphones.
This function requires the optional additional interfaces (R&S FPL1000-B5).
This function is not available for Spectrum Emission Mask measurements or measure-
ments on I/Q-based data.
The sweep stops at the frequency determined by marker 1 for the selected time and
the RF signal is demodulated in a bandwidth that corresponds to the RBW. Alterna-
tively, demodulation can be activated continuously, i.e. audio output occurs regardless
of the marker position and the marker stop time. For measurements in the time domain
(zero span), demodulation is always continuous.
Optionally, a minimum level ("Squelch Level") can be defined so that the signal is only
demodulated when it exceeds the set level. This is useful during continuous demodula-
tion to avoid listening to noise.
