The difference between the Cont peak and the Signal Track
The Cont peak focuses on the searching 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 was enabled
as well as set the frequency of this point as the center frequency.
2.5.4.7 Search Para
Defines the conditions of peak search for various peak searching. A real peak should
meet the value of both “PK Excursn” and “PK Thresh”.
1.
PK Excursn
Sets 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.
