QPSK EVM Measurement
Marker
Marker X Axis Value (Remote Command Only)
Sets the marker X Axis value in the current marker X Axis Scale unit. It has no effect if the control mode
is
Off, but is the SCPI equivalent of entering an X value if the control mode is Normal or Delta.
This parameter has different meaning between the cases where the marker trace is set to I/Q Polar and
others. In the I/Q Polar Graph, X Axis Value is also the measured value and this command is query only.
Notes 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, reference value of the selected marker appears on the Active
Function area. It is:
Marker Chip Value, at I/Q Polar
Marker X Axis Value, at EVM, Phase Error and Mag Error
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.
If the selected marker’s trace is I/Q Polar, Delta is not supported. If DELTa is
selected on the marker of the I/Q Polar, the command is ignored.
