The HP / Agilent 34901A module for the 34970A 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. Two and four wire channels can be mixed on the same module. Two additional fused inputs (22 channels total) route up to 1A of current to the internal DMM, allowing ac and dc current measurements without the need for external shunt resistors.
Features:
20 Channel Multiplexer
60 ch/s scanning
Two- and four-wire scanning
Built-in thermocouple reference junction
300 V switching
