TEST SET MODULE ASSEMBLIES

8-16TEST SET MODULE	The following paragraphs provide instructions for removing and re-
ASSEMBLIES	placing the RF/microwave components that comprise the Test Set
	Module .

Equipment Required:

Connector torque wrench (516 in), ANRITSU Model 01-201, or equivalent.

Open-end wrench, 1 in.

CAUTION

Throughout these procedures, always use the 516 in. con- nector torque wrench for connecting the Test Set Module semi-rigid coaxial lines and RF/microwave components.

Use of improper tools may damage the connectors, result- ing in degraded instrument performance.

Preliminary:

Switch373XXA power off. Remove the power cord.

Remove all covers (paragraph 8-3).

Transfer Switch Use the following procedure to remove/replace the Transfer Switch, which is common to all 373XXA models.

Procedure:

Step 1. For all models except 37269B: disconnect the semi-rigid co- axial line W87 from the input connector of the Transfer Switch. See Figure 8-11.

For Model 37269B: loosen the two screws that fasten the Transfer Switch mounting plate to the test set tray before disconnecting the semi-rigid coaxial line (W80). See Fig- ure 8-12.

Step 2. Disconnect the Transfer switch.

Step 3. Carefully flex (do not bend) the rigid-coaxial lines to gain access to the lower connectors of the Transfer Switch; see Inset A on Figure 8-11. Remove rigid-coaxial lines from these connectors.

Step 4. Disconnect the Transfer Switch power cable at connector J5 of the A17 Motherboard PCB. Free the cable by separating it from the cable harness and by temporarily removing the A24 VME Terminator PCB.

Step 5. Remove the two screws that fasten the Transfer Switch mounting plate to the test set tray, and lift the Transfer Switch assembly from the Test Set Module.
