Agilent Technologies 856290216 service manual Replacement without Contact Removal Tool

Procedure 14. W3 Line Switch Cable

3.From the bottom side of the spectrum analyzer, insert the contact end of W3 through the slotted opening in the main deck. W3 should come through to the top side of the spectrum analyzer between the Al8 CRT assembly and the post-accelerator cable.

4.Place LED AlWlDSl into the line-switch assembly.

5.Attach the line-switch assembly into the front frame, using the captive panhead screw. Ensure the connection of the line-switch grounding lug to the screw.

6.Dress W3 between the main deck standoff and the side frame. See Figure 4-25.

7.On the top side of the spectrum analyzer, redress W3.

8.Insert the four contacts into the W3 connector.

9.Attach the cable to the connector housing using the supplied tie wrap.

10.Connect W3 to A6J2. Dress W3 into the slotted opening in the deck.

11.Connect AlAlWl to A3J602.

12.Secure the power-supply cover shield to the power supply, using three flathead screws. One end of the cover fits into a slot provided in the rear frame assembly. Ensure that the extended portion of the cover shield is seated in the shield wall groove.

13.Redress W3 and the other cable assemblies down between the CRT assembly and the power supply cover such that the W9 wires are below the surface of the power-supply cover.

14.Fold up the A2, A3, A4, and A5 assemblies into the spectrum analyzer as described in “Procedure 5. A2, A3, A4, and A5 Assemblies Replacement,” steps 5 through 10.

15.Fold up Al4 and Al5 assemblies as described in “Procedure 9. Al4 and Al5 Assemblies Replacement,” steps 9 through 11.
