HP 3314A Manual

Model 3314A
C. Disconnect all five cables from the A3 PC
Assembly.
D. Remove all eight screws that secure the A3 PC
Assembly to the deck.
E. Carefully lift the A3 PC Assembly straight up.
There are three transistors mounted on the deck that
connect to the A3 PC Assembly via three connectors on
the left side of the PC board.
F. Unsolder the collector of A3Q115 and the end of
A3R146 that is nearest Q112.
G. Solder a Tie Point (0360-0124) into the empty holes
created in step F.
H. Wrap the lead from A3Q115 around its tie point.
This lead should make one full turn around the tie point
to insure good mechanical contact and the lead should
have a slight bend to relieve any stress.
I. Wrap the lead from A3R146 around its tie point.
This lead should make one full turn around the tie point
to insure good mechanical contact and the lead should
have a slight bend to relieve any stress.
J. Install about .6 inch of flexible tubing on each lead
of АЗСЕ 123.

from the tie point. See Figure 2-4, “A3CR123
Installation.”
M. Solder the leads to each tie point.
N. Remove the solder flux from both sides of the A3
PC Assembly with flux remover.
O. Carefully install the A3PC Assembly back into the
3314A. Make sure the leads from 0100, Q101 and 0108
are correctly seated in their respective connectors and
are not bent. When the A3 PC Assembly is correctly in-
stalled, each transistor lead will show about .05 inch
above the connectors.
P. Complete the assembly of the 3314A by reversing
the actions taken in steps D, C, B and then A.
2-12. HOW TO INSTALL OPTION 001
A. Remove the power cord.
B. Remove the top and bottom covers.
C. Install the A5 PC assembly onto the AI VCO shield
using the four screws and washers supplied. Make sure
that the two adjustment holes in the A5 PC Board align
with the holes in the shield.
D. Install the X3 Power Supply Cable, 03314-61616,
from А511 to A3J102.
E. Remove the temporary plug from the X3 Output
hole in the rear panel.
F. Install the X3 BNC jack, 1250-1717, in the X3 Out-
put hole. If you do not have a socket type wrench to
tighten the nut properly, you will have to remove the
rear
panel.
The
rear
panel
is
secured
to
the
rear
frame
with two screws from the top and two screws from the
bottom.
G. Install the X3 Output Cable, 03314-61611, from
‚А534 to the X3 Output jack just installed. Install the
rear panel if removed in step F.
H. Using a razor or sharp knife, carefully cut the tub-
ing that secures the two SMB connectors located in the
middle
of
the
Main
Output
Cable.
It
is
not
necessary
to
remove the tubing, just to disconnect the SMB connec-
tors.
I. Connect each SMB connector from the Main Out-
put
Cable
to
a
corresponding
SMB
connector
on
the
X3
PC Assembly.
J.
Dress
the
cables
so
that
they
are
not
stressed
and
so
that
they
will
not
interfere
with
the
fan
blades.
