which has the maximum y-axis value for that marker’s trace.

Command
:CALCulate:FLATness:MARKer[1]|2|...|12:MAXimum
Example
:CALC:FLATness:MARK2:MAX
The command SYST:ERR? can be used to query the errors to determine if a peak is found. The message
“No peak found” will be returned after an unsuccessful search.
Next Peak
Pressing Next Peak moves the selected marker to the peak that is next lower in
amplitude than the current marker value. If there is no valid peak lower than the
current marker position, a “No peak found” message is generated and the marker is
not moved.
If the selected marker was off, it is turned on as a normal marker and a peak search
is performed.
