Catalog Description

Keysight Technologies (formerly Agilent) 34921A

Mainframe required. Also see KT-34980A, KT-34921T, and KT-Y1136A.

KT-34921T terminal block is not included with the KT-34921A module and must be
added as a seperate line item.

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 1A 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.
