3.2 Swept SA Measurement
The following query is provided for backwards compatibility with ESA and PSA. It is
recommended that you use :CALC:DATA:PEAK instead.
Returns the signal peaks by frequency or by amplitude. This query uses only Trace 1
data. The sort mode is determined by :TRACe:MATH:PEAK:SORT. The commands
:CALCulate:MARKer:PEAK:EXCursion and
:CALCulate:MARKer:PEAK:THReshold are used to determine what is a signal
peak. To query 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 Peak Threshold (if Threshold is ON) and have an excursion
above Peak Excursion (if Excursion is ON)

:TRACe:MATH:PEAK[:DATA]?
Query Number of Peaks Found (Backwards Compatibility Remote Query Only)
Provided for backwards compatibility with ESA and PSA. It is recommended that you
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 query uses only Trace 1 data.
Example
:TRAC:MATH:PEAK:POINts?
Identifies the number of peaks of trace 1 that are above Peak Threshold (if Threshold is ON) and have an
excursion above Peak Excursion (if Excursion is ON)

3.2.7.5 Properties
The controls on this tab are used to set certain properties of the selected marker.
Marker Frequency | Time
This is the fundamental control that you use to move a marker around on the trace.
It is the same as "Marker Frequency | Time" on page 309 on the Settings tab.
Relative To
Selects the marker to which the selected marker is relative (its reference marker).
