When
the adjustments to
A channel have been
completed connect the cable from the Type
105
to
the B channel input
connector
and
proceed
with the
adjustments
for
this channel.
See the
charts below
for the adjustments to
each channel. Note: When the
.5 VOLTS/CM
position
is
reached the 5XT attenuator must
be
removed.

to the channel B
input
connector of the
Type

and the plug-in
unit. Adjust the Approximate Amplitude

on
the Type 107
for
3 cm
of vertical deflection
on
the

of the oscilloscope.
Adjust the
Approximate
Frequency control for an approxi
mate output frequency of 450 kc.
Now
adjust L3364,
L4374, L4362, L4372,
L4334
and L4354 for an optimum square
comer
with
no
overshoot on the square-wave
signal.
Set the
MODE switch of the Type CA Unit
to
A
ONLY and connect the Type 107, in the
same
manner
as
above, to the A channel
vertical
input connector. For channel A
adjust
L3362,
L3372, L3354 and L3334 for an optimum
square comer with no
overshoot on the square
wave
signal.
Note
When you
are finished check to
see
that
the plugs
in the coils are
all
approximately the same depth
