:TRACe:MATH:PEAK[:DATA]?
Syntax
:TRACe:MATH:PEAK[:DATA]?
Description
Queries the frequencies (Hz) and amplitudes (the unit is the same as the current Y-axis unit) of the peaks in
the peak table.
Remarks
This command only queries Trace 1.
Return Format
The query returns the frequencies and amplitudes of the peaks in the peak table in the following format. At
most, 20 pairs of frequencies and amplitudes can be returned.
For example, 1.000000000e+09,-1.463000000e+01,9.999890000e+08,-4.172000000e+01.
:TRACe:MATH:PEAK:POINts?
Syntax
:TRACe:MATH:PEAK:POINts?
Description
Query the number of peaks in the peak table.
Return Format
The query returns an integer ranging from 0 to 20.
