FFT represents FFT mode, the event table data in CSV format followed behind. The specified format of the
event table data is automatically adapted by different devices. The data are separated by commas and will
automatically line wrap according to the decoding list.

FUNCtion:FFT:MARK:THReshold:
LEVel
Command format
：
:FUNCtion:FFT:MARK:THReshold:
LEVel
<value>
:
FUNCtion:FFT:MARK:THReshold:
LEVel
?
Functional description
：
This command is used to set threshold voltage value of threshold spectrum mark.
<value>
：
Threshold voltage value, unit is V if vertical direction is Vrms. And the range is 1 mVrms~100 KVrms;
unit is dB if vertical direction is dBVrms. And the range is -60 dB~100 dB; if the unit is not matched with the
vertical unit, the setting is invalid.
Return format
：
Query returns the threshold value of spectrum mark in scientific notation, unit is related
to :FUNCtion:FFT:VTYPe.
For example
：
:FUNCtion:FFT:MARK:THReshold:LEVel -12.5dB
Set the threshold of spectrum mark to -12.5 dB.
:FUNCtion:FFT:MARK:THReshold:LEVel?
Query returns -1.250e-001.
:FUNCtion:FFT:MARK:THReshold:LEVel 0.15V
Set the threshold of spectrum mark to 0.15 V.
:FUNCtion:FFT:MARK:THReshold:LEVel?
Query returns 1.500e-001.

FUNCtion:FFT:MARK:MANUal:PEAK
Command format
：
:FUNCtion:FFT:MARK:MANUal:PEAK
Functional description
：
This command is used to move the marker to the maximum peak.
For example
：
:FUNCtion:FFT:MARK:MANUal:PEAK
Move the marker to the maximum peak.
