4.1.8.2 Pk Threshold
Specifies the minimum signal level for the analyzer internal peak identification routine to
recognize as a peak. To be considered a peak, a signal must rise above the
value by at least the value specified in

:CALCulate:MARKer[1]|2|3|4:PEAK:THReshold?
Remote Command Notes: CALC:MARK:PEAK:SEAR:MODE must be set to PARameter if
you want peak search to take advantage of the threshold excursion.
Example: :CALC:MARK:PEAK:THR -60 dB m sets the threshold to -60 dBm.
