:CALCulate:FFT:HSPan
Syntax
:CALCulate:FFT:HSPan <span>
:CALCulate:FFT:HSPan?
Description
Set the horizontal scale of the FFT operation result.
Query the current horizontal scale of the FFT operation result.
Parameter
Name Type Range Default
<span> Real
The current FFT sample rate of the
screen/200 to the current FFT
sample rate of the screen/20
5MHz/div
Note:
The step is 1X-2X-5X-10X within the range.
The current FFT sample rate of the screen =the number of points per grid horizontally/horizontal
time base. For the horizontal time base, refer to the
:TIMebase[:MAIN]:SCALe command.
You can use the
:CALCulate:FFT:HSCale command to set the horizontal scale of FFT operation
indirectly.
Return Format
The query returns the current horizontal scale in scientific notation and the unit is
Hz/div.
Example
:CALCulate:FFT:HSPan 2500000
The query returns 2.500000e+06.
