3 Short-Range Comms & IoT Mode
3.4 HRP UWB Demodulation Measurement
Command
:CALCulate:HUWB:MARKer[1]|2|…|12:REFerence?
Example
:CALC:HUWB:MARK3:REF 2
:CALC:HUWB:MARK3:REF?
Notes Range (for SCPI command): 1 to 12. If the range is exceeded the value is clipped
A marker cannot be relative to itself so that choice is not available, and if sent from SCPI generates
error -221: “Settings conflict; marker cannot be relative to itself”
When queried a single value is returned (the specified marker numbers relative marker)
Couplings The act of specifying the selected marker’s reference marker makes the selected marker a Delta
marker
If the reference marker is Off, it is turned on in Normal mode at the delta marker location
Preset The default value of the reference marker of the specified marker is its next higher numbered marker
(current marker +1). For example, if marker 2 is selected, then its default reference marker is marker 3.
The exception is marker 12, which has a default reference of marker 1
Set to defaults by Restore Mode Defaults. Not reset by Marker Off, All Markers Off, or Preset
State Saved Saved in instrument state. Not affected by Marker Off, Preset or power cycle
Min 1
Max 12
Annunciation Appears in the marker label of a Delta marker
Marker Trace
Selects the trace on which the specified marker is placed. A marker is associated
with only one trace. This trace is used to determine the placement, result, and X axis
scale of the marker. All markers have an associated trace.
When the auto initialize function is on, the marker’s trace attribute is determined
automatically by the instrument whenever the marker is switched on (Normal or
Delta) from the Off state. The marker goes to the trace in the window that has the
focus, or onto the RF spectrum window if the metrics window has the focus. For the
traces on the demod waveform window, only the demod waveform trace can be set
automatically as a marker trace, not the average/min/max demod trace.
Specifying a marker trace manually will switch off the auto initialize for the marker.
The marker’s state stays after the change of its trace.
