d. ADJUST—Grid Bias (R851) for a visible dot. Then
back off the Grid Bias potentiometer until the dot just
disappears.
e. Disconnect the 50 0 termination from the EXT
Z AXIS INPUT connector.
3. Adjust Astigmatism (R874)
a. Set:
A INTENSITY
Visible display
X-Y
Off (button out)
Channel 1 AC-GND-DC
DC
A SEC/DIV
5 ^
b.
Connect the leveled sine-wave generator output via
a 50 Q cable and a 50 D termination to the CH 1 OR X
input connector.
c.
Set the generator to produce a 50 kHz, 4-division
display.
d.
ADJUST—Astig (R874) and the front-panel FOCUS
control for the best defined waveform.
e. Disconnect the test equipment from the instrument.
4. Adjust Trace Alignment
a.
Position the trace to the center horizontal graticule
line.
b.
ADJUST—The front-panel TRACE ROTATION con
trol for optimum alignment of the trace with the center hor
izontal graticule line.
5. Adjust Geometry (R870)
a. Set:
CH 1 VOLTS/DIV
50 mV
A SEC/DIV
0.1 ms
b.
Connect 50
ns
time markers from the time-mark
generator via a 50 Q cable and a 50 ft termination to the
CH 1 OR X input connector.
c.
Adjust the Channel 1 POSITION control to position
the baseline part of the display below the bottom horizon
tal graticule line.
d.
Adjust the SEC/DIV Variable control for 5 markers
per division.
e.
ADJUST—Geom (R870) for minimum curvature of
the time markers at the left and right edges of the
graticule.
f. Set the Channel 1 AC-GND-DC switch to GND.
g.
ADJUST—Geom (R870) for minimum curvature of
the baseline trace when positioned at the top and bottom
horizontal graticule lines using the Channel 1 POSITION
control.
h. Set the Channel 1 AC-GND-DC switch to DC.
i.
Repeat parts e through h for optimum compromise
between the vertical and horizontal displays.
j. Disconnect the test equipment from the instrument.
