Threshold (Markers)

Default: -90 dBm deciBels referenced to a milliWatt: dB relative to 1 milliwatt dissipated in the nominal input impedance of the analyzer

When enabled, the Threshold value entered specifies the peak search threshold when using the Marker > Search > Peak Higher/Lower operations. All peaks found must be above this threshold. This threshold only applies to amplitude traces.

The Threshold and Excursion parameters don't affect Marker > Search > Peak.

If Excursion is also enabled, the minimum amplitude of a peak must be above the total of the peak threshold plus the Excursion value.
