www.keysight.com/find/ 34970A
An easy-to-use data logger for monitoring and
characterization applications
Data loggers are used to monitor multiple signals (temperature,
voltage, etc�) over extended periods of time to identify irregu-
larities� Example applications include environmental chamber
monitoring, component inspection, benchtop testing, process
troubleshooting, and temperature profiling�
The Keysight 34970A/34972A is easy to use for a multitude of
data logging and monitoring applications, either stand-alone or
with a computer� Its flexible, modular design makes it scalable
from 20 to 120 channels, and lets you add actuator, digital I/O,
and analog output channels for simple control� Its small size,
ruggedized features and USB memory port on the 34972A make
it perfect for portable
applications� Use GPIB (IEEE 488) or RS-232 interfaces
in the 34970A for legacy systems or use the 34972A with
standard LAN and USB interfaces for simple connection
to the PC and support of remote applications� The 34972A can
be set up at remote locations and accessed through the Web
interface on a network connection or through
the USB port by copying instrument configurations and measure-
ment data results to a USB flash drive�
Better measurements with fewer hassles
Tired of putting up with the mediocre measurement performance
you get with most data loggers or plug-in data acquisition
boards? The 34970A/34972A offers 6½ digits of resolution and
0�004% basic 1-year dcV accuracy�
Simplify your data gathering with
Keysight BenchLink Data Logger 3 software
Do you want PC-based data logging capability, but don’t
want to spend hours programming? The BenchLink Data
Logger 3 software is the answer� This Windows-based
application is designed to make it a snap to use your PC
for gathering and analyzing measurements� Use it to set
up your test, acquire and archive measurement data, and
perform real-time display and analysis of the incoming
measurements�
A familiar spreadsheet environment makes it easy to
configure and control your tests� And a rich set of colorful
graphics provides many options for analyzing and display-
ing your data—all with point-and-click ease� Set up multiple
graphics using strip charts, histograms, bar and scatter
charts, individual channel results, and more� And of course
you can use BenchLink Data Logger 3 to easily move data
to other applications for further analysis, or for inclusion in
your presentations and reports�
The BenchLink Data Logger software can run connected
to the computer, standalone in the instrument or even over
the network when using the LAN interface on the 34972A�
