Chapter 4 Retrofitting Options

To Retrofit the Rear Terminals (Option 060)

Assembly-Level Service Guide 4-17

4 Insert the connector-end of the W1, with the washers (H6) in place on the

connector, through the appropriate rear INPUTS opening.

5 Insert and tighten the BNC nuts (H3) to secure the coaxial cables to the rear of

the chassis.

6 Solder the lead-end of the cables to their appropriate ground and input pads on

A1 Motherboard Assembly (J16, J17)

For the Agilent 53131A/132A solder the rear chassis INPUTS 1 cable to J16 and

INPUTS 2 to J17. (See Figure 4-3B.)

For the Agilent 53181A solder the rear chassis INPUTS 1 cable to J17.

(See Figure 4-3B.)

7 Re-install the cover by performing the cover removal procedure, in Chapter 3 of

this guide, in reverse.

This completes the Rear Terminals (Option 060) retrofit procedures.

NOTE When using the front terminals of Inputs 1 and 2, the rear terminals should be

terminated with a 50-ohm load (such as part number 1250-0207). When using the rear

terminals, these loads should be placed on the front terminals, or the 50-ohm input

button selected (but not both).
