:CALCulate:FFT:HOFFset?
Description
Set the horizontal offset of the FFT operation result and the unit is Hz.
Query the current horizontal offset of the FFT operation result.
Parameter
Name Type Range Default
<offs> Real
-0.4*the current FFT sample rate of the
screen to +0.4*the current FFT sample
rate of the screen
0
Note: the current FFT sample rate of the screen = number of points per grid
horizontally/horizontal time base. For the horizontal time base, refer to
the
:TIMebase[:MAIN]:SCALe command.
Return Format
The query returns the horizontal offset in scientific notation.
Example
:CALCulate:FFT:HOFFset 10000000
The query returns 1.000000e+07.
