REMOVE AND REPLACE

SIGNAL SOURCE MODULES

Step 5. Remove the four screws that fastens the back plate of the source module chassis to the heatsink of the A21A1 PCB.

Step 6. Place the Signal Source Module on its‘ back plate.

Step 7. Unfasten the six PCB retainers on the bottom of the A21A1 PCB. (To unfasten, turn screwdriver slot 14 turn coun- ter-clockwise.) Gently separate the A21A1 PCB (including the heat sink) from the Signal Source Module.

To replace the A21A1 Source YIG Bias Control PCB assembly, perform the steps above in the reverse order.

Switched Filter Use the following procedure to remove/replace the Switched Filter as- Assembly sembly.

Procedure:

Step 1. Disconnect the power cable from connector P1 at the rear of the Switched Filter assembly. (Use a small screw driver to pry up gently at each end of the connector, as necessary.)

Step 2. Disconnect the semi-rigid coaxial lines from connector J6 (top) and connector J3 (lower-front) of the Switched Filter assembly.

Step 3. Disconnect the semi-rigid coaxial line from the RF INPUT (top) connector of the Down Converter assembly.

Step 4. Remove the two screws that fasten the Switched Filter as- sembly to the source module chassis and lift the assembly from the Signal Source Module.

Step 5. Disconnect the semi-rigid coaxial line from connector J1 (bottom) of the Switched Filter assembly. Put this coaxial line aside for re-use.

NOTE

When replacing the Switched Filter assembly, connect the semi-rigid coaxial line to the bottom connector (J1), before attaching the assembly to the Signal Source Module.

To replace the Switched Filter assembly, perform the steps above in the reverse order.

Down Converter Use the following procedure to remove/replace the Down Converter Assembly assembly.

Procedure:

Step 1. Disconnect the power cable from connector P1 at the front of the Down Converter assembly.
