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).
