CHECKOUT PROCEDURE
1. For the following procedure, an amplifier plug-in
should be in one of the vertical (left or center) plug-in
compartments and a time-base plug-in should be in the
horizontal (right) compartment.
2. Set the POWER switch to off (pushed in) and
connect the oscilloscope to a power source that meets the
voltage and frequency requirements of this instrument.
3. Turn the INTENSITY control counterclockwise and
pull the POWER switch out to turn the instrument on.
Initial Control Settings
Set the front-panel controls as follows:
NOTE
Titles for external controls of the oscilloscope are
capitalized in this procedure (e.g. INTENSITY,
POWER).
Trace
Alignment Adjustment
6. If
a free-running trace is not parallel with the
horizontal graticule lines, set the TRACE ROTATION
control (rear-panel adjustment) as follows: Position the
trace to the center horizontal line and adjust the TRACE
ROTATION control so that the trace is parallel with the
horizontal graticule lines.
Calibration Check
7. Connects 1X probe, or a test lead from the amplifier
plug-in connector to the CALIBRATOR loop.
8. Set the time-base unit triggering level for a stable
triggered display. Adjust the vertical and horizontal posi­
tion controls so that the display is centered vertically and
starts at the left edge of the graticule.
9. The display should be four divisions in amplitude
with approximately 2.5 complete cycles over 10 divisions
(for 60-hertz line frequency) shown horizontally. An
incorrect display indicates that the Oscilloscope or plug­
ins need to be recalibrated.

Intensity Adjustment
4. Advance the INTENSITY control until the trace is at
the desired viewing level. Set the trace near the graticule
center
line.
Focus Adjustment
5. Adjust the FOCUS control fora sharp, well-defined
trace over the entire trace length.
Beam Finder Check
10. Move the display off-screen with the vertical
position control.
11. Push the BEAM FINDER button and observe that
the display compresses into the screen area. Reposition
the display to screen center and release the BEAM
FINDER button. Disconnect the 1X probe or test lead.
External Intensity Input
12. Connect a 5-volt, 1-kHz sine-wave or square-wave
signal to the EXT INTENSITY INPUT connector. Also, use
the signal to externally trigger the time-base plug-in.
13. Slowly rotate the INTENSITY control
counterclockwise until the trace appears to be a series of
dimmed and
brightened segments. The brightened
segments correspond with the tops of the signal input
waveform.
14. Disconnect the signal setup.
This completes the checkout procedure for the os­
cilloscope. Instrument operations not explained here, or
operations that need further explanation, are discussed
under General Operating Information.
