3 Short-Range Comms & IoT Mode
3.2 Modulation Analysis Measurement
Next Pk Left
This control enables you to move 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
:CALCulate:EVM:MARKer[1]|2|...|12:MAXimum:LEFT
Example
:CALC:EVM:MARK2:MAX:LEFT
State Saved Not part of saved state
Minimum Peak
This control enables you to move 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.
Remote Command
:CALCulate:EVM:MARKer[1]|2|...|12:MINimum
Example
:CALC:EVM:MARK2:MIN
Notes Sending this command selects the subopcoded marker

Pk-Pk Search
Tis control enables you to find and display the amplitude and frequency (or time)
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 Fixed or Normal if it
is not already on. (These markers may be on two different traces.)
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.
