Span
Defines the span (band) around the marker for which the power is measured. The span
is indicated by lines in the diagram.
Remote command:
CALCulate<n>:MARKer<m>:FUNCtion:BPOWer:SPAN on page 1190
CALCulate<n>:DELTamarker<m>:FUNCtion:BPOWer:SPAN on page 1191
Power Mode
Defines the mode of the power measurement result.
For analog demodulation measurements, the power mode is not editable for AM, FM,
or PM spectrum results. In this case, the marker function does not determine a power
value, but rather the deviation within the specified span.
"Power"
The result is an absolute power level.
The power unit depends on the Unit setting.
"Relative
Power"
This setting is only available for a delta band power marker.
The result is the difference between the absolute power in the band
around the delta marker and the absolute power for the reference
marker (see "Reference Marker" on page 344). The powers are sub-
tracted logarithmically, so the result is a dB value.
[Relative band power (Delta2) in dB] = [absolute band power (Delta2)
in dBm] - [absolute (band) power of reference marker in dBm]
For details see "Relative band power markers" on page 543
"Density"
The result is a power level in relation to the bandwidth, displayed in
dBm/Hz.

Switching All Band Power Measurements Off
Deactivates band power measurement for all markers.

The R&S FSW provides demodulators for AM, FM and PM signals. The demodulation
marker function sends the demodulated data at the current marker frequency to the
