If "Peak excursion" is 30 dB, the peak 1 is found. If "Peak excursion" is 20 dB, also the
peak 2 and several others are found.
Remote command:
SPECtrum:MARKer:SETup:EXCursion on page 367
Distance
Defines a minimum distance between two frequencies that must be exceeded in order
to detect individual peaks.
Remote command:
SPECtrum:MARKer:SETup:DISTance on page 367
Trace Source
Selects the trace on which the markers are placed. Only active traces are available
(see "Trace mode (Clear/Write/ Max Hold/ Min Hold/Average )" on page 123).
Remote command:
SPECtrum:MARKer:SOURce on page 367
Marker Value
Determines whether the absolute measured results at each cursor position are dis-
played, or the delta between the cursors.

6.2.7 Cursor Measurements on Spectrums
Track cursors are available for spectrum data to determine the power or power density
in a specific frequency range.
6.2.7.1 Cursor Measurement Results
For the spectrum diagram, special track cursors are available. If enabled, you can
place the two cursors at any position in the spectrum. As a result, the frequency and
measured power levels of the selected trace at the crossing point with the cursors are
displayed. Both the power and the power density for each cursor are indicated. Instead
of the absolute results for the second cursor, the delta between both cursors can be
provided.
