Search the maximum/minimum peak

Search the maximum/minimum peak
The peak search function enables the main marker to be moved to the maximum or
minimum point in automatic mode.
Step 1. Activate the trace to be searched.

initialization.)
When multiple peaks are present, the main marker will go to the peak where the
measurement parameter value is maximum if the peak polarity is defined as positive. The
main marker will go to the peak where the measurement parameter value is minimum if the
peak polarity is defined as negative.
For details on the peak definition, see the description "Define the Peak" on page 232.
Step 4. In the presence of multiple peaks, use the softkey of the target menu to move the main
marker to a peak as shown below.

Search peaks in the left direction (direction of
decreasing sweep parameter values) from the
