Min Search

Search for and mark the peak with the minimum amplitude on the trace.

Peak Peak

Execute peak search and minimum search at the samt time and mark the results

with delta pair markers. Wherein, the result of peak search is marked with the

delta marker and the result of minimum search is marked with the reference

marker.

Cont Peak

Enable or disable continuous peak search and the default is Off. When enabled, the

system will always execute a peak search automatically after each sweep in order

to track the signal under measurement.

The difference between Cont Peak and Signal Track

In Cont peak, the system always searches for the maximum in the current

channel; while in Signal Track, the system will search for and mark the point

(with no more than 3 dB variation in amplitude) near the marker before Signal

Track is enabled, as well as set the frequency of this point as the center

frequency.

Search Para

Define the conditions of peak search for various peak searches. A real peak should

meet the requirements of both the “PK Excursn” and “PK Thresh”.

1． PK Excursn

Set the excursion between the peak and the minimum amplitude on both

sides of it. Peaks whose excursions are beyond the specified excursion are

treated as real peaks.
