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