12. Adjust Input Capacitors (C3322
and C4322)
Set the VOLTS/CM switches of the Type CA
Unit to .05. Apply a 1 kc Signal from the
Type 105 Square-Wave Generator to the Type
C A Plug-In, through the P52 cable, the 5XT
and capacitance standardizer. The capacitance
standardizer should be connected between the
P52 cable and the Type CA Unit with the 5XT
between the P52 cable and the capacitance
standardizer.
Attach the Type 105 to the A channel input
connector of the Type CA Unit and adjust
the Type 105 Output Amplitude fo r a deflection
o f approximately 3.5 cm on the oscilloscope’ s
c rt. Now adjust C3322 fo r Optimum flat top
on the waveform. Then connect the Type 105
to the B channel input connector of the Type
C A Unit and adjust C4322 for Optimum flat
top.
13. Adjust VOLTS/CM
Compensations
Maintain the same output frequency and
amplitude from the Type 105 Square-Wave
Generator as in Step 12. See the charts below
fo r the adjustments to each channel. Note:
When the .5 VOLTS/CM position is reached
the 5XT attenuator must be removed.

VOLTS/CM (A and B) .1
MODE B ONLY
Connect the Type 107 Square-Wave Gener­
ator to the channel B input connector of the
Type CA
Unit, installing the Terminating
Resistor between the P52 cable and the plug-in
unit. Adjust the Approximate Amplitude control
on the Type 107 for 3 cm of vertical deflection
on the crt 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
corner with no overshoot on the square-wave
Signal.
Set the MODE switch of the Type CA Unit
to A O N LY and connect the Type 107, in the
same manner as above, to the A channel
vertical input connector. F or channel A adjust
L3362, L3372, L3354 and L3334 for an Optimum
square corner 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
inside the coil form. If they aren't
readjust
until this condition is
obtained.
