34970A Data Acquisition/Switch Unit
The Agilent 34970A is a high perfor-
mance, low-cost data acquisition
and switching mainframe ideal
for data logging, data acquisition,
and general-purpose switching and
control applications. It consists
of a half-rack mainframe with an
internal 6

/
2
digit (22 bit) digital
multimeter. Three module slots
are built into the rear of the unit
to accept a combination of switch
and control modules. Whether you
need a few channels of simple data
logging or a hundred channels of
ATE performance, the 34970A
meets your data acquisition needs
at a price that meets your budget.
Measurements You Can Trust
The 34970A incorporates the
measurement engine from our
best-selling benchtop digital
multimeter (DMM). You get
the benefit of proven Agilent
performance, universal inputs
with built-in signal conditioning,
and modular flexibility, all in a
low-cost, compact data acquisition
package. The 34970A features
6

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.
Custom Configurations That
Grow With You
Three module slots and eight switch
and control modules allow you to
customize the 34970A to meet your
unique requirements. Buy only
what you need, and add more
modules later as your application
grows. Measure up to 120 inputs
with a single half-rack unit.
Free BenchLink Software Simplifies
Your Data Gathering
If you want PC-based data logging
capabilities, but don’t want to
spend hours programming,
BenchLink Data Logger is the
answer. 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. A rich set of
colorful graphics provides many
options for displaying your data –
all with point-and-click ease. Set up
multiple graphics using strip charts,
histograms, or individual channel
results and more. Also use Agilent
BenchLink Data Logger to easily
move data to other applications for
further analysis, or for inclusion in
your presentations and reports.
Powerful Flexibility
The 34970A’s unique design allows
per-channel configurability for
maximum flexibility and quick,
easy setup. The internal autoranging
DMM measures 11 different functions
directly, eliminating the need for
expensive external signal condition-
ing. Temperature conversion routines
are built-in to display raw thermo-
couple, RTD, or thermistor inputs
in degrees C, F, or Kelvin. Use Mx+B
scaling to convert linear transducer
outputs directly into engineering
units. You can even set high/low
alarm limits to warn you of
out-of-tolerance conditions.
Applications
Data Logging
Configured with the 34901A
20-channel relay multiplexer, the
34970A becomes a rugged, low-cost
data logger that’s ideal for quick
tests in the lab or in the field. An
intuitive front panel with self-guiding
menus and a bright, easy-to-read
vacuum fluorescent display make
standalone set-up fast and easy.
All readings are automatically time
stamped and stored in a 50,000
reading memory — enough memory
to hold a week’s worth of data
(20 channels scanned every five
minutes). The non-volatile memory
holds your data even after power is
