Connect a 1

CH 1 input to a
line-

source.
C.
CHECK—For a
stable
display, starting on the
positive-going
slope.
q.
Connect
the calibration
generator
standard-
amplitude output to
the CH 1
input via a 50 D
bnc cable
and bnc T.
Connect the
bnc female
connection to A
External Trigger
input via a 50
Q bnc cable.
Adjust the
generator output to 50
volts.
NOTE
The
range of the
A LEVEL
control with
the A
SOURCE switch
in EXT/10 is ±20
volts (40 V
peak-
to-peak) or
greater. The applied
signal
is 50 V
peak-
to-peak.
Therefore,
untriggered operation
at both
extremes of the A
TRIGGER LEVEL
control is not
required.
r.
CHECK—
Display is
triggered along the
negative
slope of
the waveform
as the A

is
rotated.
s. Set
the A

switch to +.
t. CHECK—

e.
CHECK—For a
stable display,
starting on the
negative-going slope.
f. Disconnect
probe from the
line-frequency
source;
then from the 465B.
