Default
<n>
Discrete
{1|2|3|4}
——
<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.*/

Return
Format
The query returns the threshold in scientific notation.
Example
:MATH1:FFT:SEARch:THReshold 0.5 /*Sets the threshold of the FFT peak search to 500
mdB.*/
:MATH1:FFT:SEARch:THReshold? /*The query returns 5.000000E-1.*/
:MATH<n>:FFT:SEARch:EXCursion

<excur>
Real
0 to (8xVerticalScale)
1.8 dB
Remarks
VerticalScale indicates the vertical scale of the current source.
Return
Format
The query returns the excursion of the FFT peak search in scientific notation.
Example
:MATH1:FFT:SEARch:EXCursion 0.5 /*Sets the excursion of the FFT peak search to 500
mdB.*/
:MATH1:FFT:SEARch:EXCursion? /*The query returns 5.000000E-1.*/
