Chapter 3 To Set the Horizontal System RIGOL
MSO7000/DS7000 User's Guide 3-5
Waveform before enlargement:
The waveform in the area that is not covered by subtransparent blue in the upper
part of the screen is the waveform before enlargement. Its horizontal time base (also
called main time base) is displayed at the upper-left corner of the screen. You can
rotate the Horizontal
POSITION knob to move the area left and right or rotate
the Horizontal
SCALE knob to enlarge or reduce this area.
Note: If you need to modify the horizontal time base (also called main time base) of
the normal sweep, please disable the delayed sweep function first. Rotate the
Horizontal
SCALE knob to set the required main time base, and then
enable the delayed sweep function.
Waveform after enlargement:
The waveform in the lower part of the screen is the horizontally expanded delayed
sweep waveform. Its horizontal time base (also called the time base of the delayed
sweep) is displayed on the screen. Compared with the main time base, the time
based of the delayed sweep has increased the waveform resolution, as shown in
Figure 3-1. At this time, you can rotate the Horizontal SCALE knob to adjust
the time base of the delayed sweep, and rotate the Horizontal
POSITION
knob to adjust the horizontal position of the delayed sweep.
Note: The time base of the delayed sweep should be smaller than or equal to the
main time base.
