Agilent Technologies (HP) HP 34901A

20 Channel Multiplexer Module The Agilent 34901A is the most versatile 20 channel multiplexer module for use with 34970A / 34972A Data Acquisition/Switch Unit, for general purpose scanning. It combines dense, multifunction 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. Agilent 34901A Features 20 Channel Multiplexer Two- and four-wire scanning 300 V switching 60 ch/s scanning Built-in thermocouple reference junction Ask for HP 34901A detailed specification.
