:FFT<x>:TYPE
Function
Sets or queries the spectrum for FFT analysis.
Syntax
:FFT<x>:TYPE {CH_MAG|CS_IMAG|

Example
:FFT1:TYPE CH_MAG,1
:FFT1:TYPE?
-> :FFT1:TYPE CH_MAG,1
Description • This command results in an error on models
that are not equipped with the user-defined
computation option.
• When the spectrum is set to (
CH_MAG|CS_
IMAG|CS_LOGMAG|CS_MAG|CS_PHASE|CS_
REAL|TF_IMAG|TF_LOGMAG|TF_MAG|TF_
PHASE|TF_REAL
), use <NRf> to select the
second waveform under analysis.
