Next Pk Left
Pressing Next Pk Left moves the selected marker to the nearest peak left of the
current marker that meets all enabled peak criteria. If there is no valid peak to the
left of the current marker position, a “No peak found” message is generated, and the
marker is not moved.If the selected marker was off, then it is turned on as a normal
marker and a peak search is performed.
Remote Command

:CALC:EVMM:MARK2:MAX:LEFT
State Saved Not saved in instrument state
Minimum Peak
Moves the selected marker to the minimum y-axis value on the current trace.
Minimum (negative) peak searches do not have to meet the peak search criteria. It
just looks for the lowest y-axis value. If the selected marker is Off, it is turned on
before the minimum search is performed.

Pk-Pk Search
Finds and displays the amplitude and frequency (or time, if in zero span) differences
between the highest and lowest y-axis value. It places the selected marker on the
minimum value on its selected trace. And it places that marker’s reference marker
on the peak of its selected trace.
This function turns on the reference marker and sets its mode to Normal if it is not
already on.
The rules for finding the maximum peak are exactly the same as for Peak Search,
including the use of the peak criteria rules. However, the minimum trace value is not
required to meet any criteria other than being the minimum y-axis value in the trace.
If the selected marker is off, a delta type marker is turned on and the peak-to-peak
search is done. If the selected marker is on, but it is not a delta marker, then it is
changed to delta which turns on the reference marker if needed, and then it
performs the peak-to-peak function.
