Query Syntax

:TIMebase:UIRPosition?

Query Response

<double>

Description

Sets or returns the Delay at Reference in UI relative to the timebase position. The Delay at Reference is relative to the minimum timebase position (:TIMebase:MPOSition), instead of relative to zero. The minimum timebase position is dependent on the oscilloscope hardware as shown in the following table.

Minimum Timebase Position vs. Oscilloscope

Oscilloscope	Minimum Timebase Position
N109x-series	10 ns
N1000A DCA-X	16 ns
Simulated Module	0s

For example, for a 10 GHz signal with a DCA-X minimum position of 16 ns, we can have a Delay at Reference equal to “0 UI”, but a UI position (:TIMebase:UIPosition) of 160 UI). You can use either one these settings to shift the waveform's position on screen, however there will be an offset between these settings equal to: (minimum timebase position * symbol rate).

The timebase position, can be defined to be the display graticule's left side, center, or right side position using the :TIMebase:REFerence command. By default, the timebase position located at the upper-left corner of the display graticule as shown in the following picture. From the GUI, the Delay at Reference setting is configured in the Timebase Setup dialog. Regardless of the Timebase Units setting (:TIMebase:UNITs), this command always returns the value in units of UI.

:TIMebase:UIRPosition” is the value shown in when in pattern lock and units of UI. The value is relative to the minimum timebase position, instead of relative to zero (e.g. for a 10GHz signal with a DCA minimum position of 16ns, we can have UIRPosition = “0 UI”, but UIPosition = “160UI”). Either one can be used to shift the position on screen. There will just be an offset between their values (minTimebasePosition * SymbolRate).
