Plug-In Modules
The 34980A offers a complete selection of plug-in modules to give you
high-quality measurement, switching, and control capabilities. The plug-in
modules communicate with the main system processor via the internal digital bus.
The multiplexer modules also connect to the internal DMM via the internal Analog
Buses. Each module has its own microprocessor to offload the main system
processor and minimize backplane communications for faster throughput. See
“Introduction to the Plug-In Modules for the 34980A”
for an overview
of the available plug-in modules and their functions. Each module is shipped with
its own User's Guide.
System Cabling
Depending on your specific requirements, you can connect your device under test
(DUT) to the 34980A using several optional interconnection solutions (see
“Interconnection Solutions Overview”
on page 215). Detachable terminal blocks
are available for low-frequency modules and offer an extremely flexible method for
connecting external wiring. You can also connect to the plug-in modules directly
using standard cabling with 50-pin D-Sub and 78-pin D-Sub connectors.
Optional solder cup connector kits are also available if you choose to build your
own custom cabling.
The type of cabling that you use to connect your signals, transducers, and sensors
to the module is critical to ensure measurement integrity. Some types of
transducers, such as thermocouples, have very specific requirements for the type
of cabling that should be used to make connections. Be sure to consider the
usage environment when choosing wire gauge size and insulation qualities. Wire
insulation typically consists of materials such as PVC or PTFE. The table below
lists several common cable types and describes their typical uses.
