Check A and B Internal Triggering
a.
Connect
the output of the
leveled sine-wave
generator to the A and B External trigger inputs
via
a
50 Q
cable, Gr-to-bnc-male adapter, 50 D signal pickoff unit
(Type CT-3) THRU SIG OUT output,
Gr-to-bnc-female
adapter, 50 Q bnc cable, 2X bnc attenuator,
10X bnc
attenuator, 50 O bnc
termination
and
dual-input coupler.
b. Connect the SIG OUT 10% on the
CT-3 tot he CH 1
and CH 2 inputs via a 50 O bnc cable, 50 Ci bnc termina-
tion and dual-input coupler.
c.
Adjust the leveled sine-wave generator for
either
a
3-division,
50
kHz display and set both
VOLIS/DIV
switches
to 50
mV
(0.3
division of display), or a 5-division,
50

VOLTS/DIV switches to
50 mV
(0.5
