Description :

The Keysight Technologies 34923A module for the 34980A Multifunction Switch/Measure Unit is a high speed-multiplexer for general purpose scanning. It uses reed relays to achieve scan rates up to 500 channels-per-second. Use this module for high-throughput automated test applications as well as high-speed data logging and monitoring tasks.

Current measurements can be accomplished with user supplied shunts. Standard 50-pin Dsub connectors allow for use with standard cables, terminal blocks, or mass interconnect solutions. 2- and 4-wire channels may be mixed on the same module, or configure as an 80 1-wire multiplexer.
