This function is not available for Spectrum Emission Mask measurements or measure-
ments on I/Q-based data.

Continuous Demodulation
If activated, the signal is demodulated continuously (not only at the marker position)
and sent to the audio output. This allows you to monitor the frequency range acousti-
cally (assuming the sweep time is long enough).
For zero span and EMI measurements, demodulation is always active continuously.

Marker Stop Time
Defines how long the sweep is stopped at the marker position to output the demodula-
ted signal.
For zero span measurements, demodulation is always active continuously, regardless
of the marker stop time.
