Keysight N9923-90001 User's Guide
—Peak Excursion The vertical distance (dB) between the peak and the
valleys on both sides. To be considered a peak, data values must "fall
off" from the peak on both sides by the excursion value. Default = 0.5
dB for CAT and NA Modes; 6 dB for SA Mode.
For example, the settings for the trace in the following image are:
—Threshold: –10 dB
—Excursion: 1 dB
—Scale = 1 dB / Division.
Peak A = Valid Peak (Above Threshold and Excursion Settings)
Peak B = Invalid Peak (Below 1 dB Excursion Setting)
Peak C = Invalid Peak (Below –10 dB Threshold Setting)
Mkr ->
Mrk -> Center (Not available in DTF or SA mode with zero span) The center
frequency of the measurement becomes the value of the active marker. The
frequency span is adjusted accordingly.
Mkr -> Delay
(NA mode ONLY.) The group delay value of the active marker
becomes the electrical delay setting of the trace. Learn how to set group
