R&S FSP Remote Control – Description of Commands
CALCulate Subsystem
6.56 Operating Manual 1164.4556.12 - 06
CALCulate<1|2>:MARKer<1...4>:FUNCtion:DEModulation[:STATe] ON | OFF
This command switches on or off the audio demodulator when the indicated marker is reached in the
selected measurement window. In the frequency domain (span > 0) the hold time can be defined at
the corresponding marker position with
CALCulate:MARKer:FUNCtion: DEModulation:HOLD
.
In the time domain (span = 0) the demodulation is permanently active.
The command is only available with option audio demodulator R&S FSP-B3.
Example:
"CALC2:MARK3:FUNC:DEM ON"
'Switches on the demodulation for marker 3 in screen B.
Characteristics: *RST value: OFF
SCPI: device-specific
Mode: A
CALCulate<1|2>:MARKer<1...4>:FUNCtion:FPEaks:COUNt?
This query reads out the number of maxima found during the search. If no search for maxima has been
performed, 0 is returned.
Example:
"CALC:MARK:FUNC:FPE 3"
'searches the 3 highest maxima for trace 1
"CALC:MARK:FUNC:FPE:COUN?"
'queries the number of maxima found
Characteristics: *RST value: --
SCPI: device-specific
Mode: A
CALCulate<1|2>:MARKer<1...4>:FUNCtion:FPEaks[:IMMediate] <numeric_value>
This command searches the selected trace for the indicated number of maxima. The results are
entered in a list and can be queried with commands
CALC:MARK:FUNC:FPEaks:X?
and
CALC:
MARK:FUNC:FPEaks:Y?
. The number of maxima found can be queried with
CALC:MARK:FUNC:
FPEaks:COUNt?.
The trace to be examined is selected with
CALC:MARK:TRACe
. The order of the
results in the list can be defined with
CALC:MARK:FUNC:FPEaks:SORT
.
The number of maxima found depends on the waveform and value set for the
Peak Excursion parameter (
CALC:MARK:PEXC
), however, a maximum number of
50 maxima are determined. Only the signals which exceed their surrounding val-
ues at least by the value indicated by the peak excursion parameter will be recog-
nized as maxima. Therefore, the number of maxima found is not automatically the
same as the number of maxima desired.
