3.4.7.3 Peak Search
The controls on this tab provide a convenient way of identifying the peaks of the
signal.
When peak excursion and peak threshold are both off:
Peak Search, Continuous Peak Search, and maximum part of Pk-Pk Search will
search the trace for the point with the highest y-axis value that does not violate the
LO feedthrough rules. A rising and falling slope are not required for these three peak
search functions.
The remaining search functions Next Peak, Next Pk Right, etc., only consider trace
points that have a rising and falling slope on the left and right respectively.
NOTE
Pressing the Peak Search hardkey navigates to the Peak Search page, then
perform a peak search if the previous menu was
not
under Marker.
Marker Frequency | Time
Sets the X-axis position of the specified marker on the trace. It is the same as the
"Marker Frequency | Time" on page 490 in the Settings tab.
Peak Search
Moves the specified marker to the trace point that has the maximum y-axis value.
Remote
Command
:CALCulate:HUWB:MARKer[1]|2|…|12:MAXimum
Example
:CALC:HUWB:MARK2:MAX
:SYST:ERR?
can be used to query the errors to determine if a peak is found. The message “No peak found” will be
returned after an unsuccessful search
Next Peak
Moves the specified marker to the peak that is next lower in amplitude than the
current Y-axis value. Only peaks that meet all enabled peak criteria are considered.
