3.12 IQ Waveform Measurement
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
Backwards
Compatibility SCPI
:CALCulate:MARKer[1]|2|…|4:X:CENTer
This alias is provided for compatibility with the Band Power function in PSA and ESA
Marker X Axis Position (Remote Command Only)
Sets the marker X position in trace points. It has no effect if the control mode is OFF,
but is the SCPI equivalent of entering a value if the control mode is Normal or Delta.
The entered value is immediately translated into the current X Axis Scale units for
setting the value of the marker.
Remote
Command
:CALCulate:WAVeform:MARKer[1]|2|…|12:X:POSition <real>
:CALCulate:WAVeform:MARKer[1]|2|…|12:X:POSition?
Example
:CALC:WAV:MARK:X:POS 500
:CALC:WAV:MARK:X:POS?
Notes The query returns the marker’s absolute X-Axis value in trace points if the control mode is POSition,
or the offset from the marker’s reference marker in trace points if the control mode is DELTa. The value
is returned as a real number, not an integer, corresponding to the translation from X-Axis Scale units to
trace points
Preset After a preset, all markers are turned OFF, so the query returns a Not A Number (NAN)
