Return
Format
The query returns 1 or 0.
Example
:MATH1:FFT:SEARch:ENABle ON /*Enables the FFT peak search.*/
:MATH1:FFT:SEARch:ENABle? /*The query returns 1.*/
:MATH<n>:FFT:SEARch:NUM

——
<num>
Integer
1 to 15
5
Return
Format
The query returns an integer ranging from 1 to 15.
Example
:MATH1:FFT:SEARch:NUM 10 /*Sets the maximum number of the FFT peak search to
10.*/
:MATH1:FFT:SEARch:NUM? /*The query returns 10.*/
:MATH<n>:FFT:SEARch:THReshold
