RIGOL

:MATH:FFT:WINDow

Syntax
:MATH:FFT:WINDow <wnd>
:MATH:FFT:WINDow?
Description
Set or query the window function of the FFT operation.
Parameter
Name
<wnd>
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 waveform to be measured and its
characteristics.
Return
The query returns RECT, BLAC, HANN, HAMM, FLAT or TRI.

Command

:MATH:FFT:SPLit

Syntax :MATH:FFT:SPLit <bool>
:MATH:FFT:SPLit?
Description
Enable or disable the half-screen display mode of the FFT operation, or query the status
of the half display mode of the FFT operation.
Parameter
Name
<bool>
Explanation
Enable the half-screen 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-screen display mode (full-screen 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
The query returns 0 or 1.
