The 34980A Multifunction Switch/Measure Unit is a high-performance, cost-effective switch and measurement solution for medium-density to high-density switch/measurement applications such as design verification, functional testing, and data acquisition. It provides up to 560 2-line multiplexer channels or 1024 matrix crosspoints, and 11 measurements including temperature, AC or DC voltage, resistance, frequency, current, and special measurements. The instrument features built-in signal conditioning and modular flexibility to provide the required resolution, repeatability, speed, and accuracy.
The 34980A provides flexible switching and measurement capabilities in a compact 8‑slot chassis. It supports up to 560 two‑wire multiplexer channels or 1024 matrix cross‑points, and offers 19 interchangeable modules for custom configurations. Built‑in Ethernet, USB 2.0 and GPIB interfaces enable easy integration with test systems.
The unit includes an internal 6½‑digit DMM with 11 measurement functions, programmable I/O, and optional RF/microwave modules. Remote access is available via a web‑based interface, and the system supports SCPI programming, IVI, LabVIEW, and other common test software. This manual is written in Chinese.
