To Specify the Horizontal Reference
The horizontal reference is the reference position according to which the screen
waveform is expanded or compressed horizontally when using HORIZONTAL
SCALE to modify the horizontal time base.
Note: You can only set the horizontal reference when the “Y-T” mode is used and the
delayed sweep is on.
Press MENU (in the horizontal control area (HORIZONTAL))  HorRef, turn the
multi-function knob to select the desired horizontal reference position and press
the knob to select this position (the default is the screen center). You can also press
HorRef continuously to switch the current horizontal reference position.
 Screen Center: when changing the horizontal time base, the waveform displayed
is expanded or compressed horizontally relative to the center of the screen.
 Trigger Position: when changing the horizontal time base, the waveform is
expanded or compressed horizontally relative to the trigger point.
 User-defined: when changing the horizontal time base, the waveform is
expanded or compressed horizontally relative to the user-defined reference
position.
When “User” is selected, press RefPos and turn the multi-function knob to
set the user-defined reference position. The adjustable range is from -350 (the
rightmost) to 350 (the leftmost). The default is 0 (screen center). Pressing the
multi-function knob
can quickly reset the reference position to 0.
