Peak Search

Places a marker on the highest peak based on the settings of

the “Search Criteria” on page 104. Refer to “Peak Search

Type ” on page 105, for more information on the effect of

settings.

Peak Search Performs peak search as described above.

Key access:

Next Peak Places the marker on the next highest peak. The signal peak

must exceed the peak threshold value by the peak excursion

value. If there is no peak, the marker will not move.

Key access:

Next Pk Right Moves the marker to the next peak to the right of the

current marker. The signal peak must exceed the peak

threshold value by the peak excursion value. If there is no

peak to the right, the marker will not move and the “ No

Peak Found ” error message will appear on the display.

Key access:

Next Pk Left Moves the marker to the next peak to the left of the current

marker. The signal peak must exceed the peak threshold

value by the peak excursion value. If there is no peak to the

left, the marker will not move and the “No Peak Found” error

message will appear on the display.

Key access:

NOTE

All peak search functions ignore the LO feed through. The process for

determining if the Peak is the LO feed through takes into account Start

Frequency, Span, Resolution Bandwidth, Resolution Bandwidth shape

factor, and Frequency Accuracy. If there is no point of inflection within the

LO feed through range, the point on the trace with maximum amplitude,

that is higher in frequency than the LO feed through, will be selected.
