The Keysight 34901A module for the 34970A/34972A 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.

Price and performance beyond compare
Go ahead and compare the Keysight Technologies, Inc. 34970A and 34972A Data Acquisition/Switch Units with other data acquisition systems currently available. You’ll find it hard to come up with a system that offers the powerful measurement performance, flexibility, connectivity
options and ease of use of the 34970A/34972A—even in systems costing three to five times as much. What can you expect from a data
acquisition system that’s this affordable?

Measurements you can trust
We took the measurement engine from our best-selling benchtop DMM and embedded it inside a 3-slot mainframe. You get the benefit of proven Keysight measurement performance, universal inputs with built-in signal conditioning, and modular flexibility, all in a low-cost, compact data
acquisition package. The 34970A/34972A features 6½ digits (22 bits) of resolution, 0.004% basic dcV accuracy, and ultra-low reading noise. Combine that with scan rates of up to 250 channels/sec, and you’ve got the speed and accuracy you need to get the job done right the first time.
