Agilent 34980A Multifunction Switch/Measure Unit Data Sheet Challenge the Boundaries of Test Agilent Modular Products
High-performance switch/measure unit provides a low-cost, highly flexible measurement platform If you use automated test equipment for design validation or manufacturing, you now have a cost-effective solution for many test system applications. The 34980A multifunction switch/measure unit provides functionality that is easy to set up and use, with a fast startup time. The 34980A helps you lower your cost of test and accelerate your test-system integration and development.
Easier signal routing with four 2-wire internal analog buses. You can route your measurements directly to the internal DMM, or you can connect to external instruments through the analog bus connector on the rear of the mainframe. And since you have four 2-wire buses, you can dedicate one bus for use with the internal DMM and use the other three buses for module extensions or additional signal routing between modules, reducing your wiring needs.
Standard interfaces take the hassle out of connecting to your PC Standard Ethernet, USB and GPIB interfaces are included in every mainframe. Use one of the built-in interfaces that is already available in your computer, or if you prefer, GPIB is still available. • USB offers the quickest and easiest connection scheme—it’s perfect for small systems and bench connections. • Ethernet offers high-speed connections that allow for remote access and control.
Free BenchLink Data Logger Software to Simplify data logging The BenchLink Data Logger software for the 34980A provides a convenient way to collect and analyze your data. This is a Windows® -based application that uses a familiar spreadsheet environment to define measurement data to be collected. The tab-based format makes it easy to set up and initiate scans. Simply identify the measurements you want to acquire, initiate the process and see the data displayed real-time.

Mix and match 34980A modules to create your own custom configuration The 34980A mainframe holds up to eight plug-in modules. Mix and match them to create a custom system to meet your switching and system control needs. You can easily add or replace modules as your needs change. Table 1.
34980A multiplexer switch modules H The 34980A multiplexer modules can be used to connect one of many different points to a single point. You can connect to an external instrument, or scan multiple analog signals to the internal DMM.
Multiple multiplexers can connect to the built-in analog buses, allowing you to scan up to 560 2-wire channels or 640 1-wire channels in a single mainframe. The 34921A also offers 4 channels for directly measuring current. Or if you need more current channels, shunts can be added to the terminal block for easy current measurements. The multiplexer modules feature breakbefore-make connections to ensure that no two signals are connected to each other during a scan.
