CALCulate<1|2>:MARKer<1 to 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.
Note:
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 values at least by the value indicated by the peak
excursion parameter will be recognized as maxima. Therefore, the number of maxima found is not
automatically the same as the number of maxima desired.
Example: "INIT:CONT OFF" 'switches to single-sweep mode
"INIT;*WAI" 'starts measurement and synchronizes to end
"CALC:MARK:TRAC 1" 'sets marker 1 in screen A to trace 1
