Peak Search
Pk Threshold
Turns the peak threshold requirement on/off and sets the threshold value. The peak threshold
value defines the minimum signal level (or min threshold) that the peak identification algorithm
uses to recognize a peak.
When both Pk Excursion and Pk Threshold are on, a signal must rise above the Pk Threshold
value by at least the Peak Excursion value and then fall back from its local maximum by at least the
Peak Excursion
value to be considered a peak.
For example, if a threshold value of –90 dBm is selected, the peak search algorithm will only
consider signals with amplitude greater than the –90 dBm threshold. If a threshold value of –90
dBm is selected, and Peak Excursion is On and set to 6 dB, the peak search algorithm will only
consider signals with amplitude greater than the –90 dBm threshold which rise 6 dB above the
threshold and then fall back to the threshold.

Remote Command :CALCulate:MARKer:PEAK:THReshold <ampl>
:CALCulate:MARKer:PEAK:THReshold?
:CALCulate:MARKer:PEAK:THReshold:STATe OFF|ON|0|1
:CALCulate:MARKer:PEAK:THReshold:STATe?
Example CALC:MARK:PEAK:THR:STAT ON turns on the threshold criterion.
CALC:MARK:PEAK:THR –60 dBm sets the threshold to –60 dBm.
Dependencies When Ref Level Offset changes, Peak Threshold must change by the same amount.
Preset –90.0 dBm
ON
State Saved Saved in instrument state.
Min The current displayed Ref Level – 200 dB. The current displayed Ref Level is the current Ref
Level, offset by the Ref Level Offset.
Max The current displayed Ref Level. This means the current Ref Level, offset by the Ref Level Offset.
Default Unit depends on the current selected Y axis unit
