:MATH<n>:FFT:SEARch:EXCursion
Syntax :MATH<n>:FFT:SEARch:EXCursion <excur>
:MATH<n>:FFT:SEARch:EXCursion?
Description
Sets or queries the excursion of the FFT peak search.
Parameter
Name
Type
Range
Default
<n> Discrete {1|2|3|4}
——
<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.*/
:MATH<n>:FFT:SEARch:ORDer
Syntax :MATH<n>:FFT:SEARch:ORDer <order>
:MATH<n>:FFT:SEARch:ORDer?

Return
Format
The query returns AMP or FREQ.
Example
:MATH1:FFT:SEARch:ORDer AMPorder /*Sets the sequence of the FFT peak search
results to AMPorder.*/
:MATH1:FFT:SEARch:ORDer? /*The query returns AMP.*/

Remarks  MSO5000-E provides 4 practical filters (Low Pass Filter, High Pass Filter, Band
Pass Filter, and Band Stop Filter), which can filter the specified frequencies in the
signal by setting the bandwidth. You can use the
:MATH<n>:FFT:SOURce
command to set or query the channel source of the filter.
 LPASs: indicates low pass filter, which only allows the signals whose frequencies
