## Description

Selects the horizontal reference position to be located at the graticule's left side, 1st division, center, or right side.

The `:TIMebase:POSition` value is the location of the reference with respect to the trigger (t=0).

You can adjust the `:TIMebase:POSition` value to, in essence, move the trigger position about the reference location. When the `:TIMebase:POSition` value is zero, the trigger position is the same as the horizontal reference location.
