NOTE. Vertical positioning is a display function. Changing position simply
moves the ground reference level of a group above or below the zero position
level (center screen). You also can adjust the group position by adjusting the
offset using the Vertical Controls menu (discussed later in this article). See
NOTE on page 3–10.
To quickly determine the vertical scale for the selected group, check the Vertical
Readout at the bottom of the display. It lists each group by number and lists the
last and first channel of each group.
If the group display mode is Analog, the readout also shows the group volts/
division setting. If the group display mode is Off, BusForm, or Timing Diagram,
OFF, Bus, or Timing replaces its volts/division readout. (See Figure 3-4.)
NOTE. The Vertical Readout varies its display based on the logic scope setup.
See To Check Group Settings on page 3–56 for a complete description of the
Vertical Readout.
To check on overall vertical setup, press SHIFT
(main) Groups (side).
To access the Vertical Controls menu, press GROUP MENU
Controls (main). (See Figure 3-4.) Use this menu to set vertical offset and
bandwidth (full or limited) of the selected group. You can also change the
vertical position to a specific number of divisions from center screen from this
menu instead of using the Vertical POSITION knob.
To include or eliminate the higher frequency components, change the bandwidth
of the selected group.
1. Press GROUP MENU
2. Toggle Bandwidth (side) to Full or 20 MHz.
To set the vertical position, press GROUP MENU
(main) Position (side) and use the general purpose knob or keypad to set
position in divisions. Press Set to Position 0 divs (side) if you want to reset the
position of the selected group to center screen.
