R&S ESCI CALCulate:FEED Subsystem

CALCulate:FEED Subsystem
The CALCulate:FEED subsystem selects the type of evaluation of the measured data. This corresponds
to the selection of the Result Display in manual mode.
If the FM demodulator is active, the selection of the type of evaluation is independent of the
measurement window. Therefore, the numeric suffix <1|2> is irrelevant and ignored.
Command Parameter Unit Comment
CALCulate<1|2>
:FEED <string> no query
CALCulate<1|2>:FEED <string>
This command selects the measured data that are to be displayed.
Parameters for option R&S FS-K7 FM Demodulator:
<string>::=
'XTIM:AM' Demodulated AM signal in level display.
Equivalent to 'XTIM:RFPower'.
'XTIM:RFPower[:TDOMain]' Demodulated AM signal in level display.
'XTIM:RFPower:AFSPectrum<1...3>' AF spectrum of demodulated AM signal;
results referenced to trace 1 to 3.
'XTIM:FM[:TDOMain]' Demodulated FM signal.
'XTIM:FM:AFSPectrum<1...3>' AF spectrum of demodulated FM signal;
results referenced to trace 1 to 3.
'XTIM:SPECtrum' RF spectrum of FM signal determined from the measured data by
means of FFT.
'XTIM:PM[:TDOMain]' Demodulated PM signal.
'XTIM:PM:AFSPectrum<1...3>' AF spectrum of demodulated PM signal;
results referenced to trace 1 to 3.
'XTIM:AMSummary<1 to 3>' AM results, referred to trace 1 to 3.
'XTIM:FMSummary<1 to 3>' FM results, referred to trace 1 to 3
'XTIM:PMSummary<1 to 3>' PM results, referred to trace 1 to 3
