Atec Agilent-34980A - Manual (Page 19)

34959A breadboard module
Use this module to create your own
custom designs inside the 34980A
mainframe. You can control your
custom circuits with access to both
the +12 V and +5 V supplies, 32 relay
drive lines and two 8-bit GPIO ports.
Your design can be isolated from the
analog buses or connected by loading
the backplane switches. Simply
mount your custom PC board or other
components into the space provided
and connect via the two ribbon
connectors provided. The module is
provided with two 50- or 78-pin Dsub
connector openings. For custom
connections, use the detachable flat
faceplates for easy modification.
You can program your circuitry using
standard read and write commands
in SCPI.
