Mean Trace Data; Query The Signal Peaks; Query Number Of Peaks Found; Peak Sorting - Agilent Technologies ESA-E Series Programmer's Manual

Language Reference
TRACe Subsystem
Destination traces are: TRACE1|2|3, LLINE1, LLINE2, and
RAWTRACE
Source traces are: TRACE1|2|3, LLINE1, LLINE2, and
RAWTRACE
Example:
:TRAC:MATH:ADD TRACE2,TRACE1,TRACE3
is equivalent to : (trace 2 = trace 1 + trace 3)

Mean Trace Data

:TRACe:MATH:MEAN? <trace>
Returns the mean of the amplitudes of the trace amplitude elements in
measurement units.
Traces are: TRACE1|2|3, LLINE1, LLINE2, and RAWTRACE

Query the Signal Peaks

:TRACe:MATH:PEAK[:DATA]?
Outputs the signal peaks by frequency or by amplitude. The sort mode
is determined by the command :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 get the number of signals found meeting the specified
limits, use the query :TRACe:MATH:PEAK:POINts?

Query Number of Peaks Found

:TRACe:MATH:PEAK:POINts?
Outputs the number of signal peaks identified. The amplitude of the
peaks can then be queried with :TRACe:MATH:PEAK:DATA?

Peak Sorting

:TRACe:MATH:PEAK:SORT AMPLitude|FREQuency
:TRACe:MATH:PEAK:SORT?
Determines if the signals in the :TRACe:MATH:PEAK:DATA? query are
sorted by frequency or amplitude.
Amplitude sorts the identified peaks by descending amplitude.
Frequency sorts the identified peaks by increasing frequency.
