Marker Mode
Sets the marker control mode to POSition (Normal), DELTa, or OFF. All interactions
and dependencies detailed under the control description are enforced when the
remote command is sent. If the selected marker is OFF, pressing Marker sets it to
POSition and places it at the center of the screen on the trace determined by the
Marker Trace rules. At the same time, Marker X Axis Value appears on the Active
Function area.
The default active function is the active function for the currently selected marker
control mode. If the current control mode is OFF, there is no active function, and the
active function is turned off.
