:CALCulate:FFT:VOFFset
Syntax
:CALCulate:FFT:VOFFset <offs>
:CALCulate:FFT:VOFFset?
Description
Set or query the vertical offset of the FFT operation result.
Parameter
Name Type
<offs> Real
Note: For the VScale (the vertical scale of MATH), refer to the
Return Format
The query returns the vertical offset in scientifc notation.
:CALCulate:FFT:HSCale
Syntax
:CALCulate:FFT:HSCale <hscale>
:CALCulate:FFT:HSCale?
Description
Set or query the horizontal coefficient in FFT operation. This command indirectly sets the FFT horizontal
scale.
Parameter
Name Type
<hscale> Discrete
Note: You can use the
:CALCulate:FFT:HSPan
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.
2-54
Range
-40×VScale to 40×VScale
Range
{1|2|3|4}
command to set the horizontal scale of FFT directly.
