Configuring the 34959A Breadboard Module
Accessing the 34980A Mainframe’s Analog Bus
If your custom circuitry will need access to the four Analog Buses on the
mainframe’s backplane, you must install relays (not provided) on and
make connections directly to the Agilent- supplied PC board (see the
explanation on
page 313 for PC board removal, and the table on page 318
for connection information). The following enlargement of the Analog Bus
control area of the board shows where to install the relays and make wire
connections:
Analog Bus Relay Installation and Solder Hole Locations

SHOCK HAZARD Only qualified personnel who are aware of the
hazards involved should install, remove or configure the 34959A
breadboard for the 34980A mainframe. Before touching any
installed accessory, turn off all power to the mainframe and
terminal blocks, and to all external devices connected to the
mainframe or terminal blocks.
C A U T I O N
When soldering relays to the Agilent-supplied PC board, take special
care to avoid shorts between pins. Shorting these connections may
result in damage to the breadboard module, the 34980A mainframe,
other installed modules, or your test circuitry.
