Peak Search
Set the peak search condition. The available options are Maximum and Para.
If
Max
is selected, the system searches for the maximum on the trace.
If
Para
is selected, the system searches for the peak that meets the
parameter condition on the trace.
Note:
This setting applies only to the peak search executed by pressing
Peak
at the front panel; while other searches such as Next Peak, Peak Right, Peak
Left and Min Search are all based on the
Para
.
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 10 peaks can be
displayed in the table.
