Marker - Keysight x-series User Reference Manual

Marker

This displays a menu that enables you to set the marker control mode to Normal, Delta or Off.
If the selected marker is Off, pressing Marker sets it to Normal and places it at probability of 10–1 (Or at a
point after the probability of 10–1 if the latter point does not exits) on the trace determined by the Marker
Trace rules. At the same time, the Marker X Axis Value appears on the Active Function area.
The Active function for the selected marker's current control mode is the default active function. If the
current control mode is Off, there is no active function and the active function is turned off. The active
function display is the marker X axis value entered in the active function area, which will display the marker
value to its full entered precision.
All interactions and dependencies detailed under the key description are enforced when the remote
command is sent.

If the selected marker is Off, pressing Marker sets it to Normal and places it at the center of the
screen on the trace determined by the Marker Trace rules. At the same time, the Marker X Axis
Value appears on the Active Function area.
Default Active Function: the active function for the selected marker's current control mode. If the
current control mode is Off, there is no active function and the active function is turned off.
Active Function Display: the marker X axis value entered in the active function area will display the
marker value to its full entered precision.

If no suffix is sent, it will use the fundamental units for the current marker X Axis Scale. If a suffix is
sent that does not match the current marker X Axis Scale unit, an error "Invalid suffix" will be
generated.
The query returns the marker's absolute X Axis value if the control mode is Normal, or the offset from
the marker's reference marker if the control mode is Delta. The query is returned in the fundamental
units for the current marker X Axis scale: Hz for Frequency, seconds for Time, dB for Amplitude. If the
