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

Connect the Type 107
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
comer with no overshoot on the square-wave
signal.

et 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
inside the coil form. If they aren't
readjust until this condition is
obtained.

Ad j ust the Type 190 Constant Amplitude
ignal Generator to obtain an output frequency
of 50 kc. Attach the Type 190 to the B channel
vertical input connector installing the 5XT
between the 190 attenuator box and the plug ­
in. Adjust the Output A mpl itude control on the
Type 190 to obtain exactly 3 cm of vertical
deflection on the crt. Adjust the Type 190
for an output frequency of 24 m c making sure
not to move the Output Amplitude control.
There should now be at least 2.1 cm of vertical
deflection remaining.
Turn the MODE switch to A ONLY and
connect the Type 190 to the B channel vertical
input connector. Make sure not to disturb the
control settings of the Type 190 when making
this transfer. The A channel should also have
at least 2.1 cm of vertical deflection.
