peak. To get the number of signals found meeting the specified limits, use
:TRACe:MATH:PEAK:POINts?
Example
:TRAC:MATH:PEAK?
Identifies the peaks of trace 1 that are above the Peak Threshold (if Pk Threshold is ON) and have an
excursion above the Peak Excursion (if Pk Excursion is ON)

:TRACe:MATH:PEAK[:DATA]?
Query Number of Peaks Found (Remote Query Only)
Provided for backwards compatibility with ESA and PSA. For new designs, use
:CALC:DATA:PEAK instead.
Returns the number of signal peaks identified. The amplitude of the peaks can then
be queried with :TRACe:MATH:PEAK:DATA? This command uses only Trace 1data.
Example
:TRAC:MATH:PEAK:POINts?
Identifies the number of peaks of trace 1 that are above the Peak Threshold (if Pk Threshold is ON) and
have an excursion above the Peak Excursion (if Pk Excursion is ON)

3.1.7.5 Properties
The controls on this tab are used to set certain properties of the selected marker.
Marker Frequency
This is the fundamental control that you use to move a marker around on the trace.
It is the same as "Marker Frequency" on page 204 in Settings.
Relative To
Lets you select the marker to which the selected marker is relative.
Every marker has another marker to which it is relative. This marker is referred to as
the reference marker for that marker. This attribute is set by the Marker, Properties,
Relative To key. The marker must be a DELTa marker to make this attribute relevant.
If it is a DELTa marker, the reference marker determines how the marker is
controlled and how its value is displayed. A marker cannot be relative to itself.
