Key Reference
Peak Search
Pk-Pk Search
Finds and displays the frequency (or time, if in zero span),
and amplitude differences between the highest and lowest
trace points.

Continuous Pk
On Off
When
Continuous Pk
is
on
, the marker will remain on the peak
signal even if the frequency of that signal changes. The
marker will remain on that signal as long as the amplitude
of the signal does not change by more than 3 dB from one
sweep to another.
If the signal is lost, the marker will attempt to find it again
and maintain on the peak. If there are other signals on
screen near the same amplitude, one of them may be found
instead. Signals near 0 Hz cannot be maintained effectively.
This function is intended to maintain the marker on signals
with a frequency that is changing, and an amplitude that is
not changing.

Peak Table
Peak Table
Displays a list of up to ten signal peaks that is
updated at the end of each sweep. The peaks can be sorted
in order by descending amplitude or by ascending frequency.
Peaks above or below the display line can be excluded from
the table. The peak table function works with trace 1 only.
