Keysight Technologies 34901A

The Keysight (formerly Agilent) 34901A is the most versatile multiplexer for general-purpose scanning.

The multiplexer module for 34970A and 34972A data acquisition/switch units helps access the internal digital multimeter (DMM). It combines dense, multi-function switching with scan rates of 60 channels per second 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.

Applications

You can use the Keysight (formerly Agilent) 34901A multiplexer module to connect to the internal DMM of the 34970A data acquisition system. You can also use this module with the 34972A model data logger.

Accessories

• One 34901A, 20-channel multiplexer
• Functional test certificate

34901A, 34902A, or 34908A: Which Multiplexer Should You Choose?

For broad functionality, use the 34901A module, and for high scanning speeds, turn to the 34902A. The 34908A gives you a single-ended density, while the 34901A and 34902A allow multi-channel closures, which the 34908A does not allow.

These three low-frequency multiplexers are the only modules you can use to connect to the internal DMM of the Keysight 34970A and 34972A data logging instruments.
