Adjust Each Waveform
Each example waveform group contains only one channel that, in turn, contains
only one waveform. Thus, adjusting a group is the same as adjusting a
waveform.
Do the following steps to select each waveform individually and to adjust its size
and placement. Refer to Figure 1-10 for knob locations.
1. Press GROUP 1. Note the logic scope displays the waveform of the selected
group “highlighted” on screen.
2. Turn the vertical SCALE knob clockwise. Observe the change in the
selected waveform and the group readout at the bottom of the display.
3. Turn the vertical POSITION knob first one direction, and then the other.
Observe the change in the displayed waveform, and note the group indicator
at the left side of the graticule moves with the group. (Also note the group
indicator of the selected group appears in reverse video. (See Figure 1-9.)
Then return the waveform to the center of the graticule.
4. Turn the horizontal SCALE knob one click clockwise. Observe the time
base readout at the bottom of the display. With the time base set to
250
m
s/div now, you should see two complete waveform cycles on the
display.
