TRACe Subsystem
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
Query the Signal Peaks
:TRACe:MATH:PEAK[:DATA]?
Outputs the signal peaks by frequency or by amplitude. This command uses only
trace1 data.
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? This command uses only trace1
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.
Smooth Trace Data
:TRACe:MATH:SMOoth <trace>
Smooths the trace according to the number of points specified in
:TRACe:MATH:SMOoth:POINts. There is no equivalent front panel function.
Traces are: TRACE1|2|3, and RAWTRACE commands.
