tionality is active.

4.6.3 Marker Functions – MKR FCTN Key
In spectrum analysis mode the MKR FCTN menu offers further measurements with
the markers. In IF analysis the functionality is limited.
Select the spectrum analysis mode for the following functions:
• Measurement of noise density ( NOISE MEAS softkey)
• Measurement of phase noise ( PHASE NOISE softkey)
• Measurement of filter or signal bandwidth ( N DB DOWN softkey)
• Activating of AF demodulation ( MARKER DEMOD softkey)
On calling the menu, the entry for the last active marker is activated ( SELECT
MARKER softkey); if no marker is activated, marker 1 is activated and a maximum
search ( PEAK softkey) is performed. The marker can be set to the desired trace by
means of the MKR->TRACE softkey.
