FFT are not suitable.
<value> represents CHANnel<n>. <n> take value from 1/2/3/4{CH1/ CH2/ CH3/ CH4}.
Return format
：
Query returns CHANnel1, CHANnel2, CHANnel3 or CHANnel4.
For example
：
:FUNCtion:SOUR1 CHAN1
Set channel 1 as the first source.
:FUNCtion:SOUR1?
Query returns CHANnel1.
:FUNCtion:SOUR2 CHAN2
Set channel 2 as the second source.
:FUNCtion:SOUR2?
Query returns CHANnel2.
:FUNCtion:OPERation ADD
Add channel of source 1 and channel of source 2.
:FUNCtion:FFT:WINDow
Command format
：
:FUNCtion:FFT:WINDow {RECTangular|HANNing|HAMMing|BMAN}
:FUNCtion:FFT:WINDow?
Functional description
：
FFT add window to intercept signal. RECT, HANN, HAMM, BMAN is respectively rectangular window,
Hanning window, Hamming window and Blacman window.
Return format
：
Query returns {RECTangular|HANNing|HAMMing|BMAN}.
For example
：
:FUNCtion:SOUR1 CHAN1
Set channel 1 as the source.
:FUNC:FFT:WIND HAMM
Add Hamming window.
:FUNC:FFT:WIND?
Query returns HAMMing.
:FUNCtion:FFT:DISPlay

{FULL| SPLIt| WATerfall1| WATerfall2}
:
FUNCtion:FFT
:
DISPlay
?
Functional description
：
This command is used to set FFT display mode.
Return format
：
Query returns {FULL| SPLIt| WATerfall1| WATerfall2}. FULL is full display, SPLIt is split screen display.
WATerfall1 is waterfall curve 1, WATerfall2 is waterfall curve 2.
For example
：
:
FUNCtion:FFT
:
DISPlay
FULL
Set FFT to full display.
:
FUNCtion:FFT
:
DISPlay
?
Return FULL.
