Measure Commands
FFT:MAGNitude
FFT:MAGNitude
Command
:MEASure:FFT:MAGNitude [<source>]
The :MEASure:FFT:MAGNitude command measures the magnitude of the FFT.
The source is specified with the :MEASure:SOURce command or with the
optional parameter following the :MEASure:FFT command.
The source must be a function that is set to FFT, or a waveform memory that
contains an FFT for this command and query to work.
<source>
{FUNCtion<N> | WMEMory<N>}
<N>
For functions and waveform memories: 1, 2, 3, or 4.
Query
:MEASure:FFT:MAGNitude?
The :MEASure:FFT:MAGNitude? query returns the magnitude value of the
FFT.
Returned Format
[:MEASure:FFT:FMAGNitude] <magnitude>[,<result_state>]<NL>
<result_state>
If SENDvalid is ON, the result state is returned with the measurement result.
See the :MEASure:RESults table in this chapter for a list of the result states.
Example
This example measures the magnitude of the peak specified by the
:meas:fft:peak for channel 4.
