——Peak Threshold
CAT mode Loss measurements are displayed in positive values. In these
cases, the Peak Threshold setting is inverted. For example, Peak Threshold
= –20 will consider any peak that has less Loss than 20 dB to be valid.

All about Markers
Peak Criteria
for CAT, IQA, NA, or SA mode:
Minimum amplitude (dB). To be considered valid, the peak
must be above the threshold level. The valley on either side can be below the
threshold level.
Default = –190 for CAT and NA Modes; –90 for SA Mode.
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.
(I/Q Analyzer Only) Enables or disables the Continuous
Peak Search marker. When Continuous Peak Search is on, a peak search is
automatically performed for the selected marker after each sweep. The rules
for finding the peak are exactly the same as for Peak Search, including the
use of peak criteria rules. See also,
Enables or disables the delta reference fixed marker.
