MODULES

placing the RF/microwave components that comprise the Signal

 

Source Module.

Equipment Required:

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

CAUTION

Throughout these procedures, always use the 516 in. con- nector torque wrench for connecting the Signal Source Module semi-rigid coaxial lines and RF/microwave compo- nents. Use of improper tools may damage the connectors, resulting in degraded instrument performance.

Preliminary:

￿Switch373XXA power off. Remove the power cord.

￿Remove all covers (paragraph 8-3).

Removal of Signal Use the following procedure to remove the Signal Source Module from Source Module the chassis. This step is necessary before any of the module compo-

nents can be removed/replaced.

Procedure:

Step 1. Place the373XXA on its top (bottom-side up).

Step 2. At J2 on the motherboard PCB, disconnect the Floppy Con- trol (ribbon) cable that goes to the floppy drive. Dress the ribbon cable away from the Signal Source Module output connector; see Figure 8-11.

Step 3. Disconnect the semi-rigid coaxial line W87* from the out- put connector of the Signal Source Module.

Step 4. Place the373XXA in normal (top-side up) position.
