HP 85106D mm-Wave System

HP 85104A Test Set Module

Troubleshooting Procedures

Swapping the Power
Divider (A6)

Procedure 4

Before beginning this procedure, turn the HP 85105A mm-wave controller
power OFF. Disconnect the HP 85104A from the HP 85105A.

Refer to the step references in Figure 5-11 on page 5-32.

1. Disassemble the test-set module using the following four steps:

a.

Invert the test set module so that the bottom side is facing up.
Remove the stand by loosening the two captive screws until the
module and stand are disengaged.

b.

Remove all extensions from the HP 85104 test set modules.

c.

Remove the two torx-head screws from the bottom housing. Pull the
bottom housing off.

d. Slide the front panel up and out. Cut and remove any cable ties as

needed.

2. Disconnect the LO IN and LO OUT cables from the power divider

(Step 18).

3. Remove the two screws from the power divider (Step 17) using the

T-8 torx-head screw driver. Slide the power divider out of the assembly.

4. Replace the power divider with a known good power divider (possibly

from the other test set module).

5. Reattach the LO IN and LO OUT cables to the power divider.

6. Reconnect the cables from the HP 85104A to the HP 85105A. Turn the

HP 85105A ON. Recheck the unratioed power levels (refer to

“Procedure 1” on page 5-11).

7. Return to the troubleshooting flowchart.
