:CALCulate:SPECtrum:MARKer:FUNCtion:PTHReshold <num>

(Read-Write) Sets and queries the peak threshold value that defines the minimum signal level (or min threshold) that the peak identification algorithm uses to recognize a peak.

Relevant Modes

IQA (Spectrum only)

Parameters

<numeric>

Minimum: -200

Maximum: 200

Couplings

For a signal to be identified as a peak it must meet certain criteria:

- Signals in the negative frequency range and signals very close to 0 Hz are ignored.

- Signal must satisfy peak excursion (:CALC:SPEC:MARK:FUNC:PEXC) and peak threshold criteria before being identified as a peak.

Examples
