Calibration—475
f. Adjust the High-Frequency signal generator for a 200
megahertz output frequency.
g. CHECK—That a stable display, with no more than 0.2
division of jitter, can be obtained on both slopes of the
displayed waveform, by adjusting the A LEV E L control, in
the AC and DC positions of the A COUPLING switch.
h. Remove the X 2 BNC attenuator from the test setup.
i. CHECK —That a stable display, with no more than 0.2
division of jitter, can be obtained on both slopes of the
displayed waveform, by adjusting the A LEV E L control, in
the LF REJ position of the A COUPLING switch.
j. Remove the X I 0 BNC attenuator and replace the X 2
BNC attenuator to the test setup.
k. Set the A SOURCE switch to E X T -M O .
I. C HECK—Repeat step 48-g.
m. Replace the X I 0 BNC attenuator to the test setup.
n. Set the H O R IZ D ISPLA Y switch to B D L Y 'D , the B
SOURCE switch to E XT, and the A SOURCE switch to
NORM.
o. CHECK—That a stable display, with no more than 0.2
division of jitter, can be obtained on both slopes of the
displayed waveform, by adjusting both LEVEL controls, in
the AC and DC positions of the B COUPLING switch.
p. Remove the X 2 BNC attenuator from the test setup.
q. CHECK—That a stable display, with no more than 0.2
division of jitter, can be obtained on the slopes of the
displayed waveform, by adjusting both LEVEL controls, in
the LF REJ position of the B COUPLING switch.
49. Check B Internal 200 Megahertz Triggering
a. Set the B SOURCE switch to NORM and both
V O L T S /D IV switches to 10 mV.
b. Adjust
the
High-Frequency
Constant-Amplitude
Signal Generator (067-0532-01) for a 1.5 division display of
a 200 megahertz signal.
c. C HECK —That a stable display, with no more than 0.2
division of jitter, can be obtained on both slopes of the
displayed waveform, by adjusting both LEVEL controls, in
the AC, LF REJ, and DC positions of the B COUPLING
switch.
d. Set the B SOURCE switch to CH 1.
e. C HECK —Repeat step 49-c.
f. Set the B SOURCE switch to CH 2.
g. CHECK —That a stable display cannot be obtained in
any position of the B COUPLING switch.
h. Set the V E R T MODE switch to CH 2.
i. CHECK —Repeat step 49-c.
j. Set the B SOURCE switch to NORM.
k. CHECK —Repeat step 49-c.
I. Set the B SOURCE switch to CH 1.
m. CHECK —Repeat step 49-g.
50. Check A Internal 200 Megahertz Triggering
a. Set the H O R IZ D ISPLA Y switch to A.
b. CHECK —That a stable display, with no more than 0.2
division of jitter, can be obtained on both slopes of the
displayed waveform, by adjusting the A LEVEL control, in
the AC, LF REJ, and DC positions of the A COUPLING
switch.
c. Set the A SOURCE switch to CH 2.
d. CHECK —Repeat step 50-b.
e. Set the A SOURCE switch to CH 1.
f. C HECK—That a stable display cannot be obtained in
any position of the A COUPLING switch.
