The Keysight 34922A module for the 34980A Multifunction Switch/Measure Unit offers high density multiplexer switching in a compact size. It combines dense, multi-function switching with 100 channel/second scan rates to address a broad spectrum of data acquisition applications.
Current measurements can be accomplished with user provided shunt resistors. Standard 78-pin Dsub connectors allow for use with standard cables, terminal blocks, or mass interconnect solutions.
