:MATH:FFT:WINDow
Syntax
:MATH:FFT:WINDow <wnd>
:MATH:FFT:WINDow?
:MATH:FFT:WINDow?
Description
Set or query the window function of the FFT operation.
Parameter

Type
Range
Default
<wnd>
Discrete
{RECTangle|BLACkman|HANNing|HAMMing|
FLATtop|TRIangle}
RECTangle
Explanation
Spectral leakage can be considerably decreased when a window function is used.
Different window functions are applicable to measure different waveforms. You need
to select the window function according to different waveforms and their
characteristics.
Return
Format
The query returns RECT, BLAC, HANN, HAMM, FLAT or TRI.
Example

Command
:MATH:FFT:SPLit
Syntax
:MATH:FFT:SPLit <bool>
:MATH:FFT:SPLit?
:MATH:FFT:SPLit?
Description
Enable or disable the half display mode of the FFT operation, or query the status of the
split display mode of the FFT operation.
Parameter
Name
Type
Range
Default
<bool>
Bool
{{0|OFF}|{1|ON}}
1|ON
Explanation
Enable the half display mode: the source channel and the FFT operation results are
displayed separately. The time domain and frequency domain signals are displayed
clearly.
Disable the half display mode (full display mode): the source channel and the FFT
operation results are displayed in the same window to view the frequency spectrum
more clearly and to perform more precise measurement.
Return
Format
The query returns 0 or 1.
Example
:MATH:FFT:SPLit OFF
