The Keysight 34970A data acquisition / data logger switch consists of a three-slot mainframe with a built-in 6 1/2 digit digital multimeter. Each channel can be configured independently to measure one of 11 different functions without the added cost or hassles of signal-conditioning accessories. Choose from eight optional plug-in modules to create a compact data logger, full-featured data acquisition system or low-cost switching unit. On-module screw-terminal connections eliminate the need for terminal blocks and a unique relay maintenance feature counts every closure on every switch for easy, predictable relay maintenance. Our most popular module 34901A features a built-in thermocouple reference and 20 two-wire channels.

Keysight’s BenchVue DAQ Control and Analysis app is available for use with the DAQ970A, 34970A, 34972A and 34980A. BenchVue gives you an intuitive interface for test configuration and real-time data display and analysis. Setup and make measurements quickly, export data or log and view real-time measurements with a variety of display types to interpret your data faster. BenchVue Software also supports many other Keysight instruments giving you a single interface for Keysight’s most popular instruments.

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

Built-in signal conditioning to get your job done
Whether you need to measure temperature, ac/dc volts, resistance, frequency, or current, the 34970A/34972A can handle it.

The internal autoranging DMM directly measures 11 different
functions, eliminating the need for expensive external signal
conditioning. And our unique design allows complete per channel
configurability for maximum flexibility and quick, easy set up. It’s
like having an independent, high-performance DMM behind each
Standard connectivity to the PC
Whether you use GPIB, RS-232, LAN or USB interfaces, the
34970A/34972A family offers easy connection to the PC. The
34970A offers traditional GPIB and RS-232 interfaces. The
34972A has built-in Gigabit LAN and USB 2.0 so you can connect
to a modern PC without having to purchase any GPIB cards,
cables or converter boxes. With the standard LAN connections
you also get the added benefit of a graphical Web interface for
easy configuration of measurements and monitoring of results
using a standard Web browser.

Convenient data storage with USB flash drive
The 34972A also features a built-in USB memory port so that
you can use a USB flash drive to upload BenchLink Data Logger
configurations into the 34972A and collect data without being
connected to a PC. Data can be logged directly to the USB
flash drive, extending your instrument’s memory, or copied from
internal memory for transfer to a computer in another location.
