:MATH:FFT:WINDow
Syntax :MATH:FFT:WINDow <wnd>
Set or query the window function of the FFT operation.
Parameter
<wnd> Discrete
{RECTangle|BLACkman|HANNing|HAMMing|
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 waveform to be measured and its
Return
The query returns RECT, BLAC, HANN, HAMM, FLAT or TRI.

Command
:MATH:OPERator
:MATH:FFT:SPLit
Syntax :MATH:FFT:SPLit <bool>
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
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.
