:MATH:FFT:HCENter
Syntax :MATH:FFT:HCENter <cent>
:MATH:FFT:HCENter?
Description Set or query the center frequency of the FFT operation result, namely the frequency
relative to the horizontal center in the screen. The default unit is Hz.
Parameter
Name
Type
Range
Default
<cent>
Real
0~( current screen sample rate×2/5)
5MHz
Explanation Current screen sample rate = 100/current horizontal timebase.
Step = horizontal scale of the FFT operation result/50.
Return
Format
The query returns the current center frequency in scientific notation.
Example
:MATH:FFT:HCENter 10000000 /*Set the center frequency to 10MHz*/
:MATH:FFT:HCENter? /*The query returns 1.000000e+07*/

Command
:MATH:OPERator
:MATH:FFT:HSCale
:TIMebase[:MAIN]:SCALe
:MATH:OPTion:STARt
Syntax :MATH:OPTion:STARt <sta>
:MATH:OPTion:STARt?
Description
Set or query the start point of the waveform math operation.
Parameter
Name
Type
Range
Default
<sta>
Integer
0~(End point currently set－1)
0
Explanation This command is invalid for FFT operation. Sending this command will modify the
start point of all operations (except FFT).
The horizontal axis of the source selected is equally divided into 1200 parts, in which
the left is numbered as 0 and the right is numbered as 1199.
Return
Format
The query returns an integer.
Example
:MATH:OPTion:STARt 50
