 LB: when the horizontal time base is modified, the waveform displayed will be
expanded or compressed relative to the left border of the screen.
 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.
The query returns CENT, LB, RB, TRIG, or USER.
:TIMebase:HREFerence:MODE TRIG /*Sets the horizontal reference mode to
trigger position.*/
:TIMebase:HREFerence:MODE? /*The query returns TRIG.*/
:TIMebase:HREFerence:POSition
:TIMebase:HREFerence:POSition <pos>
:TIMebase:HREFerence:POSition?
Sets or queries the user-defined reference position when the waveforms are expanded
or compressed horizontally.
The query returns an integer ranging from -500 to 500.
:TIMebase:HREFerence:POSition 60/*Sets the user-defined reference position to 60.*/
:TIMebase:HREFerence:POSition? /*The query returns 60.*/
:TIMebase:VERNier
:TIMebase:VERNier <bool>
:TIMebase:VERNier?
Enables or disables the fine adjustment function of the horizontal scale; or queries the
on/off status of the fine adjustment function of the horizontal scale.
The query returns 1 or 0.
:TIMebase:VERNier ON /*Sets the fine adjustment function of the horizontal
scale to ON .*/
:TIMebase:VERNier? /*The query returns 1.*/
