12. Set both Channel 1 and Channel 2 AC-GND-DC
switches to DC. Ensure that both CH 1 and CH 2 VOLTS/
DIV switches are set to 0.1
(1 X) for 2-division displays.
24. Select CH 1 VERTICAL MODE and set Channel 1
AC-GND-DC switch to DC. Recenter the display on the
screen.
13. Select BOTH and ADD VERTICAL MODE and
observe that the resulting display is 4 divisions in amplitude.
Both Channel 1 and Channel 2 POSITION controls should
move the display. Recenter the display on the screen.
Using the Horizontal Section
1. Return the SEC/DIV switch to 0.5 ms and note
the display for future comparison in step 3.
14. Press in the Channel 2 INVERT push button to invert
the Channel 2 signal.
15.
Observe that
the displ

is a
straight line,
that t

m of the
tw ‘0 sig
nals is zero.
indicating
3. Observe that the display is similar to that obtained
in step 1.
16. Set the CH 2
VOLTS/DIV switch to 50 m (1X).
17. Observe the 2-division display, indicating
algebraic sum of the two signals is no longer zero.
that the
18. Press in the Channel 2 INVERT push button again
to release it. Observe a noninverting display having a
6-division signal amplitude.
5. Push in the
SEC/DIV Variable control knob to obtain
a Xl sweep.
6. Return the
SEC/DIV switch to 0.5 ms.
19. Set both Channel 1 and Channel 2 AC-GND-DC
switches to GND.
7. Rotate the VAR
HOLDOFF control to its maximum
clockwise position.
20. Set the CH 1
VOLTS/DlV switch to 50 m (1X).
21. Select ALT VERTICAL MODE. Position the Chan-
nel 1 trace two divisions above the center graticule line and
position the Channel 2 trace two divisions below the center
graticule line.
22. Rotate the
SEC/DIV switch throughout its range
(except X-Y). The display will alternate between channels
at all sweep speeds. This mode is most useful for sweep
speeds from 0.05
pus to 0.2 ms per division.
8. Observe that the
crt trace starts to flicker as the
holdoff between sweeps
is increased.
10. Rotate the SEC/DIV Variable control out of the
CAL detent to its maximum counterclockwise position.
23. Select CHOP VERTICAL MODE and rotate the 11. Observe that the sweep rate is approximately 2.5

displayed on the screen.
unlike the ALT mode, both Channel 1 and Channel 2
signals are displayed for each sweep speed on a time-shared
basis. This mode is most useful for sweep speeds from
