:FFT<x>:RPOSition
Function Sets or queries the center point for magnifying
the vertical axis for FFT analysis.
Syntax
:FFT<x>:RPOSition {<NRf>}
:FFT<x>:RPOSition?
<x> = 1 to 2
<NRf> = −4 to 4 (divisions)
Example
:FFT1:RPOSITION 1
:FFT1:RPOSITION?
-> :FFT1:RPOSITION 1.000E+00
:FFT<x>:TRACe
Function Sets or queries the source waveform for FFT
analysis.
Syntax
:FFT<x>:TRACe {<NRf>|MATH<y>}
:FFT<x>:TRACe?
<x> = 1 to 2
<NRf> = 1 to 8
<y> = 1 to 4
Example
:FFT1:TRACE 1
:FFT1:TRACE?
-> :FFT1:TRACE 1
:FFT<x>:TYPE
Function Sets or queries the spectrum for FFT analysis.
Syntax
:FFT<x>:TYPE {CH_MAG|CS_IMAG|
CS_LOGMAG|CS_MAG|CS_PHASE|CS_REAL|
LS_IMAG|LS_LOGMAG|LS_MAG|LS_PHASE|
LS_REAL|PS_LOGMAG|PS_MAG|PSD_LOGMAG|
PSD_MAG|RS_LOGMAG|RS_MAG|TF_IMAG|
TF_LOGMAG|TF_MAG|TF_PHASE|TF_REAL
[,<NRf>|MATH<y>]}
:FFT<x>:TYPE?
<x> = 1 to 2
<NRf> = 1 to 8
<y> = 1 to 4
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.
