Horizontal Control
You can control the horizontal part of the display (the time base) using the
horizontal menu and knobs. This section describes how to use the horizontal
controls and menus.
To Check the Horizontal Status
Check the Record View to determine the size and location of the waveform
record and the location of the trigger relative to the display. (See Figure 3–30.)
Check the Time Base readout to see the time/division settings and the time base
(main or delayed) being referred to. (See Figure 3–30.) Since all live waveforms
use the same time base, the digitizing oscilloscope only displays one value for all
the active channels.
