3 VMA Mode
3.2 Custom OFDM Measurement
The SCPI command in the table below selects the marker and sets the marker
control mode as described under Normal, Delta, Fixed and Off, below. All
interactions and dependencies detailed under the control description are enforced
when the remote command is sent.
Remote
Command
:CALCulate:OFDM:MARKer[1]|2|…|12:MODE POSition | DELTa | FIXed | =OFF
:CALCulate:OFDM:MARKer[1]|2|…|12:MODE?
Example
:CALC:OFDM:MARK2:MODE POS
:CALC:OFDM:MARK2:MODE?
Couplings The marker addressed by this command becomes the selected marker on the front panel
Preset OFF
State Saved The marker control mode (Normal, Delta, Fixed, Off) and X Axis value are saved in instrument state
Range Normal|Delta|Fixed|Off
Delta Marker (Reset Delta)
Pressing this button has exactly the same effect as pressing Delta in "Marker Mode"
on page 478. 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.

All Markers Off
Turns off all markers.
Remote Command
:CALCulate:OFDM:MARKer:AOFF
Example
:CALC:OFDM:MARK:AOFF
Couple Markers
When this function is ON, moving any marker causes an equal X Axis movement of
every other marker that is not Fixed or Off. By “equal X Axis movement” we mean
that we preserve the difference between each marker’s X Axis value (in the
fundamental x-axis units of the trace that marker is on) and the X Axis value of the
marker being moved (in the same fundamental x-axis units).
