:CALCulate:FFT:WINDow
Syntax
:CALCulate:FFT:WINDow <window>
:CALCulate:FFT:WINDow?
Description
Set or query the window function of the FFT operation.
Parameter
Name Type
<window> Discrete
Explanation
The window function can effectively reduce the spectrum leakage effect.

Different window function is suitable for measuring different waveform; therefore, please select the

desired window function according to the waveform to be measured and its characteristics.
Return Format
The query returns RECT, HANN, HAMM or BLAC.
:CALCulate:FFT:SPLit
Syntax
:CALCulate:FFT:SPLit <bool>
:CALCulate:FFT:SPLit?
Description
Enable or disable the split display of the FFT operation; or query the current status of the split display of
the FFT operation.
Parameter
Name Type
<bool> Bool
Explanation
ON: the source channel waveform and the FFT operation results are displayed separately. The time

domain and frequency domain signals are displayed clearly.
OFF (Full Screen): the source channel waveform 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.
