3 VMA Mode
3.1 Digital Demod Measurement
3.1.8.3 Peak Search
The controls on this tab enable you to move the marker to selected peaks of the
signal, giving you enormous analysis capabilities, particularly when combined with
the Delta Marker function.
Marker X
Sets the X Axis value of the selected marker in the current X Axis Scale unit. This is
the same as "Marker X" on page 289 on the Settings tab.
Peak Search
Moves the selected marker to the trace point that has the maximum y-axis value for
that trace.
NOTE
Pressing the Peak Search hardkey automatically moves you to the Peak Search
page of the Marker menu and performs a Peak Search.
Remote Command
:CALCulate:DDEMod:MARKer[1]|2|…|12:MAXimum
Example
:CALC:DDEM:MARK2:MAX
Notes Sending this command selects the subopcoded marker
Next Peak
Moves the selected marker to the peak that is next lower in amplitude than the
current marker’s value. Only peaks which meet all enabled peak criteria are
considered. 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.
In Digital Demod measurements, if the format is complex (vector or constellation),
then the marker moves to the closest point that has a lower magnitude than the
marker's current position.
If the selected marker was off, then it is turned on as a Normal marker and a peak
search is performed.
Remote Command
:CALCulate:DDEMod:MARKer[1]|2|…|12:MAXimum:NEXT
Example
:CALC:DDEM:MARK2:MAX:NEXT
Notes Sending this command selects the subopcoded marker
