center horizontal graticule line. This sets the zero reference
for the display.
4. Return the Channel 1 input coupling to AC. Notice that the
square wave is centered vertically on the screen. Now set
the input coupling to DC and observe what happens to the
waveform. The zero reference is maintained at the center
horizontal graticule line.
NOTE
More information about using the controls is con¬
tained at the end of this procedure. Refer to it
when needed while learning the front-pane! con¬
trols.
5. Use the following controls and notice the effect each has on
the displayed waveform as the settings are changed.
Each POSITION control
CH 1 VOLTS/DIV
CH 1 VOLTS/DIV Variable (CAL)
SEC/DIV Variable (CAL)
HORIZONTAL MODE
HORIZONTAL MAG
TRIGGER SLOPE
6. At this point, connect the second signal adapter to the CH2
or Y input connector. Set the VERTICAL MODE selector to
CH 2 and TRIGGER SOURCE to CH 2, then follow steps 2
through 5 again, using the Channel 2 controls.
7. Now set the VERTICAL MODE selectors to BOTH-NORM-ALT
and return both VOLTS/DIV controls to .2 V (1X). Rotate ait
variable controls clockwise to their CAL detents. Set the
TRIGGER SOURCE switch to CH 1. Then use the VERTICAL
POSITION controls to position the two traces to convenient
locations on the screen.
8. While watching the Channel 2 waveforms, set the middle
VERTICAL MODE control to CH 2 INVERT and notice the ef¬
fect. Then set the right MODE to ADD. What happens to the
control waveforms? Finally, return the middle MODE control
to NORM. What waveform is displayed now?
