Removing and Replacing the A27, A28, A29, and A30 First Converters (Mixers) and Mixer Bias Board E8362B, E8363B, E8364B

Removing and Replacing the A27, A28, A29, and A30
First Converters (Mixers) and Mixer Bias Board

Tools Required

• T-10 TORX driver (set to 9 in-lb)

• T-20 TORX driver (set to 21 in-lb)
• 5/16-inch open-end torque wrench (set to 10 in-lb)
• ESD grounding wrist strap

Removal Procedure

Refer to

for this procedure.

1. Disconnect the power cord.

2. Remove the outer cover. Refer to

“Removing the Covers” on page 7-6

. Position the

analyzer bottom side up and raise the receiver deck as shown. Refer to

Removing the Receiver Deck” on page 7-8

if necessary.

3. With a 5/16-inch torque wrench, disconnect the eight semirigid cables (item

①

) and the

four flexible cables (item

②

).

CAUTION

Be careful not to damage the center pins of the semirigid cables. Some flexing
of the cables is necessary to remove the assembly. Do not over-bend them.

4. With a T-10 TORX driver, remove the four mounting screws (item

③

).

5. Remove the mixer bracket and disconnect the ribbon cable (item

④

). Observe the

CAUTION

above.

6.

If replacing a first converter (mixer):

a. Remove the defective mixer from the bracket by removing the attachment screws.

b. Install the new mixer onto the bracket using the attachment screws from the mixer

that was removed. Be careful to properly align the DC feed-through pins.

If replacing the mixer bias board:

a. Remove all four mixers from the bracket by removing the attachment screws.

b. Remove the mixer bias board by removing the attachment screws.

c. Install the new mixer bias board onto the bracket by

loosely

installing the

attachment screws from old the mixer bias board. Do not tighten them at this time.

d. Reinstall the four mixers using their original attachment screws. Be careful to

properly align the DC feed-through pins.

e. Using a T-10 TORX driver, tighten the mixer bias board attachment screws.

Replacement Procedure

1. Reverse the order of the removal procedure.

2. Perform the post-repair adjustments, verifications, and performance tests that pertain

to this removal procedure. Refer to

Table 7-2 on page 7-80
