:FUNCtion:FFT:WINDow
 Command format：
:FUNCtion:FFT:WINDow {RECTangular|HANNing|HAMMing|BMAN}
:FUNCtion:FFT:WINDow?
 Functional description：
FFT windowing to intercept signal. RECT, HANN, HAMM, BMAN is rectangular window,
Hanning window, Hamming window and Blacman window respectively.
 Return format：
Query return {RECTangular|HANNing|HAMMing|BMAN}.
 For example：
:FUNCtion:SOUR1 CHAN1 set channel 1 as source 1
:FUNC:FFT:WIND HAMM windowing Hamming window
:FUNC:FFT:WIND? query return HAMMing
:FUNCtion:FFT:VTYPe
 Command format：
:FUNCtion:FFT:VTYPe {VRMS|DBRMS}
:FUNCtion:FFT:VTYPe?
 Functional description：
Set unit of FFT vertical diection as dbrms or VRMS. dbrms presents root mean square of power;
VRMS presents root mean square of voltage.
 Return format：
Query return VRMS, DBRMS.
 For example：
:FUNCtion:SOUR1 CHAN1 set channel 1 as source 1
:FUNC:FFT:VTYP VRMS
set unit of FFT vertical direction as root mean square of voltage
:FUNC:FFT:VTYP? query return VRMS
:FUNCtion:FFT:FREQuency
 Command format：
:FUNCtion:FFT:FREQuency?
 Functional description：
The center frequency of spectrum and waveform after obtaining FFT.
 Return format：
Query return 1.000e003，unit is Hz.
 For example：
