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.
