Specification and Performance Check-5110
PERFORMANCE CHECK PROCEDURE
1. Check Trace Alignment
a. Position the horizontal trace over the center
horizontal graticule line.
b. Check—that the trace is parallel to the graticule line.
c. Adjust— the TRACE ROTATION control (rear-pane!
screwdriver adjustment) to align the trace horizontally.
2. Check Geometry
a. Press the POWER switch to turn off the os­
cilloscope.
b. Interchange the amplifier and time-base units in
their respective compartments. Pull the POWER switch to
on.
c. Position the vertical trace over the center vertical
graticule line, extending vertically above and below the
graticule area, and set the FOCUS and INTENSITY
controls for a well-defined trace.
d. Check—that vertical bowing and tilt of the trace
display is less than 0.1 division at the center line and when
positioned horizontally across the entire graticule area.
e. Press the POWER switch to turn off the oscilloscope
and interchange the amplifier and time-base units back to
their usual compartments.
f. Pull the POWER switch to on.
3. Check Beam Finder
a. Set the INTENSITY control for a dim trace.
b. Press and hold the BEAM FINDER pushbutton in,
then rotate the position control of the vertical amplifier
and time-base units fully clockwise and counterclockwise.
c. Check— that the display is intensified, compressed,
and remains within the graticule area.
d. Release the BEAM FINDER pushbutton and return
the INTENSITY control to a normal setting.
4. Check Amplifier Alternate Operation
a. Push both CH 1 and CH 2 pushbuttons in and
position the traces about two divisions apart.
b. Set the time-base unit Display pushbutton to Alter­
nate.
c. Turn the time-base Seconds/Div switch throughout
its range.
d. Check— for trace alternation at all sweep rates
(except in amplifier positions). At faster sweep rates,
alternation is not apparent; instead, the display appears as
two traces on the screen.
e. Press the POWER switch to tu rn off the oscilloscope
and change the amplifier from the vertical compartment to
the center compartment.
f. Pull the POWER switch on and repeat parts c and d
of this step.
5. Check Amplifier Chop Operation
a. Set the time-base unit Display pushbutton to Chop.
b. Turn the time-base Seconds/Div switch throughout
its range.
c. Check —for a dual-trace display at all sweep rates
(except in amplifier positions) without alternation.
d. Press the POWER switch to turn off the oscilloscope
and change the amplifier from the center compartment to
the left vertical compartment.
e. Pull the POWER switch to on and repeat parts b and
c of this step.
6. Check Chop Operation Between Amplifiers
a. Press the POWER switch to turn off the os­
cilloscope. Install a second vertical dual-trace plug-ln unit
in the center plug-in compartment and set its controls for
dual-trace operation. Pull the POWER switch to on.
b. Turn the time-base Seconds/Div switch throughout
its range.
c. Check—for two traces for each amplifier (one for
each channel) at all sweep rates.
NOTE
If
it
single-channel amplifier is used instead of the
second dual-trace amplifier, the single-channel
trace will appear once per sweep.
7. Check Alternate Operation Between Amplifiers
a. Set the time-base Display pushbutton to Alternate
and the Seconds/Div switch to 50 ms.
b. Check—for two traces for the left amplifier (one for
each channel), then two traces for the right amplifier,
alternately between amplifier units.
