Pk-Pk Search
Executes Peak Search and Minimum Peak functions at the same time, and marks the
results with the Delta marker. Wherein, the result of Peak Search is marked with the
reference marker and the result of Minimum Peak is marked with the Delta marker.
Cont Peak
Enables or disables continuous peak search. By default, it is Off. When it is enabled,
after finishing each sweep, the analyzer will automatically execute one peak search
operation to track the measurement signal.
When the marker is a fixed type, the Cont Peak menu is grayed out and disabled. The
signal track and continuous peak functions are mutually exclusive. Once either of
them is enabled, the menu of the other one will be grayed out. When the Cont Peak
function is on, if the current marker is off, set the marker to Position mode, and then
execute the peak search operation.
Difference between Cont Peak and Signal Track
In Cont Peak, the system always searches for the maximum in the current
frequency 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, and then set the frequency of this point to be the center
frequency.
Peak Config
1. Peak Threshold
Specifies the minimum value of the peak amplitude. Only when the peak is
greater than the peak threshold, can it be judged as a peak.
