## Query Syntax

    :WMEMoryN:XREFerence?

Where N identifies one of eight {1:8} possible waveform memories. For example, `:WMEMory4`.

## Description

Queries the horizontal reference (`LEFT` or `CENTer` of the display) which is stored for the waveform in memory. The horizontal reference marks the trigger event and may or may not be the same as Infiniium's current setting. The horizontal position is the time delay relative to the trigger event (`:WMEMory:XPOSition`) relative to the trigger event. The horizontal reference and position of the original waveform was set with the `:TIMebase:REFerence` and `:TIMebase:POSition` commands.
