Summary
Although the 3499A/B/C Switch/Control system has been a great addition to many test systems, the new 34980A now offers an even better module selection plus measurement capability, standard PC connections for communication, and is easy to connect to modules. The wide offering of
Features that differentiate new 34980A:
•FET switches for long life, high speed measurement scans and the latest in technology Armature and Reed relays for both Multiplexer and Matrix switching
•Analog bus for joining modules, connecting to external instruments, accessing internal DMM.
•Up to 5A general purpose switch addresses the most common high power and device control applications.
•Bread board with +12V and +5V supplies for more design flexibility.
•Integrated DMM and measurement capability save you time versus programming with an external measurement instrument, and money with the switch and DMM in one instrument.
•Up to 1000 readings/sec scan rate for higher speed applications
•GPIB and new USB and LAN interfaces provide flexibility, lower cost, higher data transfer rates, and are the emerging trend of choice of interfaces.
•Up to 70 Ch per module offer higher density solutions
•Standard module connectors & cables offer an easy connection and for Mass interconnect solutions.
•Screw terminals with latching mechanisms are easy to remove and replace and securely fastened when in use.
•Web interface to quickly and easily test or debug the test system switching.
•Large memory buffer for acquired measurements.
There are a few specialized features the 3499 offers that are not available with the new 34980A. It is good to be aware of the differences as you upgrade to the newer system.
3499A/B/C differentiating features
•4 dig I/O ports built into mainframe doesn’t require a module
•
•1000V multiplexer module
The 34980A Switch/Measure unit can be used in the same applications as the 3499A/B/C including design verification, functional test and data acquisition applications. It can also be used in many new applications such as for data logging, as a data acquisition system and/or as a switch system. It can even provide a solution for applications requiring transducer- based measurements such as thermocouple or strain. The 34980A offers a great switch, measurement and test system control solution at a great value.
