Agilent 34921A 40-Channel Armature Multiplexer w/ 34921T for 34980A
Agilent 34921A 40-Channel Armature Multiplexer w/ 34921T for 34980A
Product Overview
The Keysight 34921A module for the 34980A Multifunction Switch/Measure Unit is the most versatile multiplexer for general purpose scanning. It has low thermal offset characteristics and a built-in thermocouple reference on the terminal block, making it ideal for temperature measurements directly to the internal DMM. The dense, multi-function switching with 100 channel/second scan rates addresses a broad spectrum of data acquisition applications.
Four additional fused inputs (44 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. Standard 50-pin Dsub connectors allow for use with standard cables, terminal blocks, or mass interconnect solutions.
