The Marker key accesses the Marker menu. A marker can be placed on a trace to allow the value of the
trace at the marker point to be determined precisely. The functions in this menu include a 1-of-N
selection of the control mode Normal, Delta, Fixed, or Off for the selected marker. 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.
Markers may also be used in pairs to read the difference (or delta) between two data points. They can be
used in Marker Functions to do advanced data processing, or to specify operating points in functions like
Signal Track and N dB Points.
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 key
description are enforced when the remote command is sent.
Marker Control Mode
Setting the Marker X-axis Value
The command below sets the marker X-axis value in the current marker X-axis scale unit. In each case
the marker that is addressed becomes the selected marker. It has no effect (other than to cause the marker
to become selected) if the control mode is
Off, but it is the SCPI equivalent of entering an X value if the
control mode is
Normal, Delta, or Fixed.
