h. Set the A SOURCE switch to CH 1.
Calibration—475
I. Replace the X I 0 BNC attenuator to the test setup.
i. CHECK—A stable display can be obtained on both
slopes of the displayed waveform in the AC, LF REJ, and
DC positions of the A C O UPLING switch by adjusting the
A LEV E L control.
j. Set the A SOURCE switch to NORM .
k. CHECK—Repeat step 45-i.
46. Check A External 40 Megahertz Triggering
a. Set the H O R IZ D IS PLA Y switch to A, the A
SOURCE switch to E X T , the B SOURCE switch to NORM,
and the CH 1 V O L T S /D IV switch to 20 mV.
b. Adjust the Medium-Frequency signal generator for a
five division display of a 40 megahertz signal.
c. Add a X2 BNC attenuator to the External Trigger
signal test setup between the X I 0 BNC attenuator and the
50 £2 BNC termination.
d. CHECK—A stable display can be obtained, by
adjusting the A LE V E L control, on both slopes of the
displayed waveform in the AC and DC positions of the A
COUPLING switch.
e. Remove the X 2 BNC attenuator from the External
Trigger signal test setup.
f. CHECK—A stable display can
be obtained, by
adjusting the A L E V E L control, on both slopes of the
displayed waveform in the LF REJ position of the A
COUPLING switch.
g. Set the A SOURCE switch to E XT -F 10.
h. Remove the X I 0 BNC attenuator from the test setup.
i. CHECK—Repeat step 46-f.
j. Replace the X 2 BNC attenuator to the test setup.
k. CHECK—Repeat step 46-d.
47. Check B External 40 Megahertz Triggering
a. Set the H O R IZ D ISPLAY switch to B D L Y 'D , the B
SOURCE switch to E XT, and the A SOURCE switch to
NORM.
b. Adjust the Medium-Frequency signal generator for a
five division display.
c. CHECK —A stable display can
be obtained, by
adjusting the L E V E L controls, on both slopes of the
displayed waveform in the AC and DC positions of the B
COUPLING switch.
d. Remove the X 2 BNC attenuator from the test setup.
e. CHECK —A stable display can be obtained, by
adjusting the LE V E L controls, on both slopes of the
displayed waveform in the LF REJ position of the B
COUPLING switch.
f . Disconnect the test setup.
48. Check External 200 Megahertz Triggering
a. Set the T IM E /D IV switch to 10jus, the T R IG MODE
switch to A U T O , the X 10 MAG button in, both V O L T S /
D IV switches to 1 V , the V E R T MODE switch to CH 1, and
the A SOURCE switch to E XT.
b. Connect the
High-Frequency Constant-Amplitude
Signal Generator (067-0532-01) to the A and B External
Trigger inputs via a 50 £2 Signal Pickoff Unit (Type CT-3),
GR-to-BNC adapter, X I 0 BNC attenuator, X 2 BNC
attenuator, 50 £2 BNC termination, and a dual-input
coupler.
c. Connect the 10% BNC output connector of the Signal
Pickoff Unit to the CH 1 and CH 2 inputs via an 18-inch
50 £2 BNC cable, a 50 £2 BNC termination, and a dual input
coupler.
d. Adjust the High-Frequency signal generator for a five
division display of a 3 megahertz signal.
e. Set the T IM E /D IV switch to 0.1
