The Keysight 34901A module for the 34970A/34972A data acquisition/switch unit is the most versatile multiplexer for general purpose scanning. It combines dense, multi-function switching with 60-channel/second scan rates to address a broad spectrum of data acquisition applications.
Mix two- and four-wire channels on the same module. Two additional fused inputs (22 channels total) route up to 1 A of current to the internal DMM, allowing ac and dc current measurements without the need for external shunt resistors.
