TEST SET MODULE ASSEMBLIES

REMOVE AND REPLACE

To replace the Transfer Switch assembly, perform the steps above in the reverse order. W111 for Models 37211B and 37217B

Input Coupler(s)/ Low Use the following procedure to remove/replace the Input Coupler(s) of Freq Bridge(s) all models 37225B through 37269B and the Low Frequency Bridges of

models 37211B and 37217B.

Procedure:

Step 1. Using a 1 in. open-end wrench, remove the front panel nut and washer of the Port1or Port2 coupler/bridge that is to be removed.

Step 2. Disconnect the two semi-rigid coaxial lines associated with the coupler/bridge (see Figure 8-11).

Step 3. Remove the two screws that fasten the coupler/bridge bracket to the test set tray. Move coupler/bridge to the rear and up to remove it from the Test Set Module.

To replace the coupler/bridge, perform the steps above in the reverse order.

Power Amplifier Use the following procedure to remove/replace the Power Amplifier as- sembly, which is common to all373XXA models.

Procedure:

Step 1. Disconnect the Power Amplifier power cable at connector J5 of the A17 Motherboard PCB. Free the cable by separat- ing it from the cable harness and by temporarily removing the A24 VME Terminator PCB.

Step 2. Disconnect the PWR AMP IN cable on the side of the Power Amplifier assembly; see Figure 8-13. (Pull out gently to dis- connect.)

Step 3. Remove the two screws that fasten the Power Amplifier as- sembly to the test set tray. Remove the two screws that fas- tens the assembly feet to the Buffer Amplifier/Sampler as- sembly.

Step 4. Disconnect the Power Amplifier from the Buffer Amplifier/Sampler by carefully pulling up on the connector end of the rigid-coaxial line from the Power Amplifier. (See Figure 8-13.) Carefully lift the assembly from the Test Set Module.

To replace the Power Amplifier assembly, perform the steps above in the reverse order.
