To Set up the Horizontal System

The oscilloscope shows the time per division in the scale readout. Since all active

waveforms use the same time base, the oscilloscope only displays one value for all

the active channels, except when using Delayed Scan, or Alternate Trigger.

The horizontal controls can change the horizontal scale and position of waveforms.

The horizontal center of the screen is the time reference for waveforms. Changing

the horizontal scale causes the waveform to expand or contract about the screen

center.

Horizontal position changes the displayed waveform position, relative to the trigger

point. Press the horizontal MENU button to display the horizontal menu as follows.

Figure 2- 37 Table 2- 19 The Horizontal menu

The parameter status symbol will be displayed on the screen during horizontal

system settings, which can help users to judge the channel status quickly.
