2.3.4.4 Next Right Peak
Search for and mark the nearest peak which is located at the right side of the current peak and meets
the peak search condition.
2.3.4.5 Peak Peak
Execute peak search and minimum search at the same 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.
2.3.4.6 Count Peak
Enable or disable continuous peak search. 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.
2.3.4.7 Peak Table
Open the peak table (in the lower window) which lists the peaks (with frequency and amplitude) that
meet the peak search condition. Up to 16 peaks can be displayed in the table.
2.3.4.8 Search Cong
Define the conditions of peak search for various peak searches. A real peak should meet the
requirements of both the “Peak Excursion” and “Peak Threshold”.
1. Peak Threshold
Assign a minimum for the peak amplitude. Peaks whose amplitudes are greater than the specified peak
threshold are treated as real peaks.
Table 2-31 Peak Threshold
Parameter Explanation
Default -140 dBm
Range -200 dBm - 200 dBm
Unit dBm
Knob Step 1 dB
Direction Key Step 5 dB
2. Peak Excursion
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.
