 RB: when the horizontal time base is modified, the waveform displayed will be
expanded or compressed relative to the right border of the screen.
 TRIG: when the horizontal time base is modified, the waveform displayed will
be expanded or compressed horizontally relative to the trigger position.
 USER: when the horizontal time base is modified, the waveform displayed will
be expanded or compressed horizontally relative to the user-defined reference
position.
Return Format
The query returns CENT, LB, RB, TRIG, or USER.
Example :TIMebase:HREFerence:MODE TRIG /*Sets the horizontal reference mode to
trigger position.*/
:TIMebase:HREFerence:MODE? /*The query returns TRIG.*/
