Chapter 3 Horizontal System Setting RIGOL

MSO4000/DS4000 User’s Guide 3-13

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.
