3 Short-Range Comms & IoT Mode
3.11 IQ Waveform Measurement
3.11.7.2 Settings
The controls on this tab include the Marker active function and a radio button
selection for "Marker Mode" on page 1583 (POSition, DELTa, or OFF) for the
selected marker, as well as additional functions that help you use markers.
Marker Time
This is the fundamental control that you use to move a marker around on the trace.
Because it is the default active function in the Marker menu, all you need to do is
press Marker and turn the knob to move the marker left and right on the display.
This is always the first control on any Marker menu page that follows the Selected
Marker.
The SCPI command sets the marker X-Axis value in the current marker X-Axis Scale
unit. 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 POSition or
DELTa.
Remote Command
:CALCulate:WAVeform:MARKer[1]|2|…|12:X <time>
:CALCulate:WAVeform:MARKer[1]|2|…|12:X?
Example
:CALC:WAV:MARK1:X 1
:CALC:WAV:MARK1:X?
Notes 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 invalid suffix message will be generated
The query returns the marker’s absolute X-Axis value if the control mode is POSition. It returns 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: seconds for Time. If the marker is OFF the
response is Not A Number
Dependencies Grayed-out, and displays three dashes, for the value when the selected Marker is OFF
Preset LTE, LTE-A, 5G NR Modes: 5ms
All other Modes: 1.0 ms
Min/Max –/+infinity
Unlike legacy instruments, where the markers were forced to be on screen, X-Series marker values
are not limited and do not clip

Compatibility SCPI
