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.
