Example
:CALC:SPEC:MARK:PEAK:THR:STAT ON
Turns on the threshold criterion
:CALC:SPEC:MARK:PEAK:THR –60 dBm
Sets the threshold to –60 dBm
Dependencies When Ref Level Offset changes, Pk Threshold must change by the same amount
Couplings Whenever you adjust the value of Pk Threshold, "Pk Threshold Line" on page 217 is turned on and, if
"Pk Excursion" on page 215 is also ON, the Peak Excursion Region is displayed
Preset –90.0 dBm
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 Ref Level Offset
Max The current displayed Ref Level. This means the current Ref Level, offset by Ref Level Offset

Pk Excursion
Lets you turn the peak excursion requirement on or off, and sets the excursion value.
The value defines the minimum amplitude variation (rise and fall) required for a
signal to be identified as peak. For example, if a value of 6 dB is selected, peak
search functions such as "Next Pk Right" on page 210 move only to peaks that rise
and fall 6 dB or more.
When both Pk Excursion and "Pk Threshold" on page 214 are ON, a signal must rise
above the Pk Threshold value by at least the Pk Excursion value and then fall back
from its local maximum by at least the Pk Excursion value to be considered a peak.
