: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<x>]}
:FFT<x>:TYPE?
<x> of FFT<x> = 1 or 2 (1 only for 2-channel
models)
<NRf> = 1 to 4 (1 or 2 for 2-channel models)
<x> MATH<x> = 1 or 2 (1 only for 2-channel
models)
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.
:FFT<x>:UNIT?
Function Queries all FFT computation unit settings.
Syntax
:FFT<x>:UNIT?
<x>= 1 or 2(1 only for the DLM2022, DLM2032,
DLM2052)
:FFT<x>:UNIT[:DEFine]
Function Sets or queries an FFT computation unit.
Syntax
:FFT<x>:UNIT[:DEFine] {<String>}
:FFT<x>:UNIT[:DEFine]?
<x>= 1 or 2(1 only for the DLM2022, DLM2032,
DLM2052)
Example
:FFT1:UNIT:DEFINE "EU"
:FFT1:UNIT:DEFINE?
-> :FFT1:UNIT:DEFINE "EU"
Description Units are applied to scale values. They never
affect the computation result.
:FFT<x>:UNIT:MODE

<x> = 1 or 2 (1 only for 2-channel models)
<NRf>=−1.0000E+31to1.0000E+31
Example
:FFT1:VERTICAL:LEVEL 1
:FFT1:VERTICAL:LEVEL?
-> :FFT1:VERTICAL:LEVEL 1.000E+00
:FFT<x>:VERTical:MODE

<x> = 1 or 2 (1 only for 2-channel models)
<NRf>=−1.0000E+31to1.0000E+31
Example
:FFT1:VERTICAL:SENSITIVITY 1
:FFT1:VERTICAL:SENSITIVITY?
-> :FFT1:VERTICAL:SENSITIVITY 1.000E+
00
:FFT<x>:VTDisplay
Function Sets or queries the on/off status of the VT
waveform display for FFT analysis.
Syntax
