Example:
CALC:FEED 'XTIM:PM:TDOM'
Switches on the PM time domain result display.
DISP:TRAC ON
Switches on the trace.
CALC:MARK:FUNC:ADEM:PM? PPE
Queries the peak value of the demodulated PM trace.
Usage:
Query only
Manual operation:
See
CALCulate<n>:MARKer<m>:FUNCtion:ADEMod:CARRier[:RESult]?
This command queries the carrier power, which is determined from the Clr/Write data.
Suffix:
<n>
.
<m>
irrelevant
Return values:
<CPower>
Power of the carrier without modulation in dBm.
Usage:
Query only
CALCulate<n>:MARKer<m>:FUNCtion:ADEMod:FERRor[:RESult<t>]?
This command queries the carrier offset (= frequency error) for FM and PM demodula-
tion. The carrier offset is determined from the current measurement data (CLR/
WRITE). The modulation is removed using low pass filtering.
The offset thus determined differs from that calculated in the
command which uses averaging to determine the frequency deviation.
Suffix:
<n>
.
<t>
<m>
irrelevant
Return values:
<CarrOffset>
The deviation of the calculated carrier frequency to the ideal car-
rier frequency in Hz.
Usage:
Query only
CALCulate<n>:MARKer<m>:FUNCtion:ADEMod:SINad:RESult<t>?
This command queries the result of the signal-to-noise-and-distortion (SINAD) mea-
surement in the specified window for the specified trace.
Note that this value is only calculated if an AF Spectrum window is displayed.
