3.6 Modulation Analysis Measurement
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.
Remote Command
:CALCulate:EVM:MARKer[1]|2|…|12:PTPeak
Example
:CALC:EVM:MARK:PTP
Notes Turns on the Marker D active function
Sending this command selects the subopcoded marker
Dependencies Pk-Pk Search is not available when Coupled Markers is on
Couplings The selected marker becomes a delta marker if not already in delta mode
State Saved Not saved in instrument state
Marker Delta
Pressing this button is exactly the same as pressing the “Delta” selection on the
Marker Mode radio button on the Settings tab. The selected marker becomes a
Delta Marker. If the selected marker is already a Delta marker, the reference marker
is moved to the current position of the selected marker, thus resetting the Delta to
zero.
The control is duplicated here in the Peak Search menu to allow you to conveniently
perform a peak search and change the marker’s control mode to Delta without
having to access two separate menus.
3.6.7.4 Properties
The controls in this tab are used to set certain properties of the selected marker.
