{CHANnel1|CHANnel2|CHANnel3|CHANnel4}
CHANnel1
Return
Format
The query returns CHAN1, CHAN2, CHAN3, or CHAN4.

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

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 waveform to be measured and its
characteristics.
Return
Format
The query returns RECT, BLAC, HANN, HAMM, FLAT, or TRI.
Example
:MATH:FFT:WINDow BLACkman /*Set the window function of the FFT operation to
blackman*/
:MATH:FFT:WINDow? /* The query returns BLACK*/
