:CALCulate:FFT:HSCale
Syntax
:CALCulate:FFT:HSCale
:CALCulate:FFT:HSCale
Description
Set the horizontal coefficient in FFT operation. This command indirectly sets the FFT
horizontal scale.
Query the current horizontal coefficient in FFT operation.

Name Type Range Default
Discrete {1|2|3|4} 1
Note: you can use the :CALCulate:FFT:HSPan command to set the horizontal scale of FFT directly.
Explanation
1: Horizontal Scale=the current FFT sample rate of the screen/20.
2: Horizontal Scale=the current FFT sample rate of the screen/40.
3: Horizontal Scale=the current FFT sample rate of the screen/100.
4: Horizontal Scale=the current FFT sample rate of the screen/200.
Return Format
The query returns 1, 2, 3 or 4.
Example
