Features
Price and performance beyond compare
Go ahead and compare the Agilent Technologies 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 Agilent 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,
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 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 fl ash 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.

Unequaled ease of use
34970A and 34972A are compatible
From the simplified configuration to the graphical Web
interface in the 34972A, we put in extra time and energy
so you don’t have to. Simple things like on-module screwterminal connectors, built-in thermocouple reference junctions, well-organized user documentation full of examples
and hints, and a standard Getting Started kit that will have
you making measurements in just a few minutes all add up
to increased productivity, whether you use the instrument
every day or only now and then.
Custom confi gurations that grow with you
Three module slots and eight switch/control modules allow
you to customize the 34970A/34972A to meet your unique
requirements. Buy only what you need—and add more
modules later as your application grows.
The 34972A LXI Data Acquisition/Switch Unit is an LXI
version of the 34970A. It replaces the GPIB and RS-232
interfaces with modern connectivity for a direct connection
to your PC or Laptop.
The 8 plug-in modules can be used with either unit—so all
the measurements and wiring are compatible. The 34972A
can be easily integrated into an existing test program with a
simple change to the instrument address. Since the 34972A
code is a superset of the 34970A code, once the instrument
address is changed, the test program will run as normal.
Example:
Change:
Set inst1.IO = ioMgr.Open(“GPIB0::9::INSTR”)

irregularities. Example applications include environmental
chamber monitoring, component inspection, benchtop testing, process troubleshooting, and temperature profiling.
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

And the 34970A/34972A measures and converts
11 different input signals:
• temperature with thermocouples, RTDs,
and thermistors
• dc and ac volts
• 2- and 4-wire resistance
• frequency and period
• dc and ac current
What’s more, each channel is independently configurable.
This means you can configure channel 1—for dcV, channel
2 for a K-type thermocouple, and channels 3 and 13 for a
4-wire RTD measurement—all on the same module, all in a
single scan. For custom linear conversions, use the Mx+B
scaling function on any channel. You can even display a
custom 3-character engineering label like RPM or PSI to
identify your measurement units.
Versatile alarms
Alarms are available on a per-channel basis as well.
Enter a high limit, a low limit, or both. The 34970A/34972A
compares each reading to its limits and flags any out-ofrange measurements. You can assign one of four TTL
alarm outputs to any input channel to trigger external
alarm lights, sirens, or send a TTL pulse to your control
system, all without a PC connected.
Monitor any input
A special display mode monitors a selected input channel,
continuously updating the display with new readings—even
during a scan. Or, when using the 34972A with built-in LAN,
the channels can be monitored over the network using the
graphical Web interface. It’s great for keeping an eye on a
key input, or for troubleshooting your system before a test.
Non-volatile memory and USB fl ash drive adds
convenience, portability
All readings are automatically time-stamped and stored in
a nonvolatile 50,000 reading memory—enough memory
to hold more than a week’s worth of data (20 channels
scanned every five minutes). The nonvolatile memory holds
your data even after power is removed, so you can use the
34970A/34972A to collect data at a remote location for
later uploading to a PC. Or if you need even more memory,
the 34972A’s USB port can be used to log data directly
to a USB flash drive or to copy the data from the reading
memory without being connected to a computer.
Data logging feature checklist
• From 1 to 120 channels of analog input
Scanning made simple
The 34970A/34972A automatically builds a scan list that
includes all configured inputs (even digital inputs from the
Agilent 34907A multifunction module) in ascending order
by channel number. You can pace scans by setting the
34970A/34972A’s internal timer for automatic scanning
at a specific interval, by manually pressing a front-panel
button, or by sending a software command or external
TTL trigger pulse.

A powerful, fl exible data acquisition system
for automated test
The 34970A/34972A gives you the resolution, accuracy,
repeatability, and speed you’ve come to expect from an
Agilent data acquisition system. It provides the measurement muscle you need, along with signal routing and
control capability, in a flexible, modular format that can
grow and change to match your varied applications.
Powerful measurements
The internal 6½ digit DMM brings the power and
performance of a world-class stand-alone DMM to the
34970A/34972A, but at a fraction of the cost and in a
fraction of the space. It’s as accurate as the best bench
DMM available: 0.004% basic 1-year dcV accuracy, 0.06%
basic 1-year acV accuracy, and 0.01% basic 1-year resistance
accuracy. Our patented Multi-slope III A-D technology
offers incredible linearity (2 ppm of reading +1 ppm of
range) along with 22 bits of real resolution. And since it is
an integrating A/D, it provides excellent noise rejection as
well—a nice change from noisy PC plug-ins and sampling
A/Ds. No more averaging lots of samples just to see the
real data you wanted. And if you need high scan rates, the
34970A/34972A is capable of delivering fully converted
measurements at speeds up to 250 ch/s.
The input section of the DMM is optically isolated and
shielded from the 34970A/34972A’s earth-referenced circuitry and computer interface, offering up to 300 V of input
isolation. This is important for reducing ground loop and
common mode voltage errors associated with long wiring
runs and floating measurement sources.
Flexible functionality
The DMM is installed inside the chassis rather than in
one of the slots, leaving all three mainframe slots free for
switch and control modules. You can choose from eight
different modules (see page 13) to get the precise functionality you need now—while giving you flexibility for future
expansion.
The internal DMM gives you the flexibility to measure
11 types of inputs easily and inexpensively. The built-in
signal conditioning and conversion routines turn raw inputs
directly into real information. Each measurement channel is
independently configurable, so you can set different measurement functions, scale factors and alarm limits, even on
adjacent channels. Advanced measurement features such
as offset compensation, variable integration time, and delay
are also selectable on a per-channel basis.
Get better measurements with built-in
signal conditioning
The Agilent 34970A/34972A architecture offers
advantages over other data acquisition solutions
which rely on external or plug-in signal conditioning
modules for handling functions other than dcV:
• Minimizes external wiring and the resultant potential for noise and errors to enter your system
• Reduces hidden costs and overall system cost by
avoiding unnecessary cables, breakout boxes and
signal conditioning elements
• Simplifies your configuration—for faster, easier
setup—with fewer connections and components
10
• Takes the guesswork out of error analysis.
Measurement accuracies are specified to include
all system-related errors
• Improves reliability, with fewer interconnects and
fewer parts that can fail
Software drivers
Your months of test system software development
time need not go to waste. Software drivers that
support (C, C#, Visual Basic, Visual Studio)®, Agilent VEE
and National Instruments LabView are available for the
34970A/34972A to make integration into your test system
easy. Standard RS-232 and GPIB interfaces on the 34970A

Customize your Agilent 34970A/34972A with
plug-in modules
A complete selection of plug-in modules gives you high
quality measurement, switching, and control capabilities to
choose from. Modules include both low-frequency and RF
multiplexers, a matrix switch, a general-purpose switch, and
a multifunction module that includes digital input/output,
analog output, and totalizer capabilities. You can mix and
match modules to get just the functionality you need right
now—then change or add more channels later as your
application grows.
More channels in less space
Surface mount construction and a highly integrated design
minimize the space required for relay drive and interface
circuitry. High density on-module connectors save both
board and connector space normally required by a terminal
block. We use the latest technology to squeeze the most
out of the remaining board space, giving you up to
40 single-ended channels in roughly the same space
used by many data acquisition system terminal blocks.
Convenient connections
Modules for the 34970A/34972A are designed to make your
testing easier, faster, and more reliable. Here’s how:

Spec interpretation guide
Example 2: Extreme operating temperature
The following pages list the technical specifications for
the Agilent 34970A/34972A Data Acquisition/Switch Unit
and its modules. The explanations and examples below
are helpful in understanding how to interpret these
specifications:
• Measurement accuracy is specified as percent of
reading plus percent of range, where reading is the
actual measured value and range is the name of the
scale (1 V, 10 V, etc.)—not the full scale value (1.2 V,
12 V, etc.).
• DMM measurement accuracies include all switching
errors. Switching errors are also listed separately in the
module specifications section. Temperature measurement
accuracies include ITS-90 conversion errors. The thermocouple accuracies include the reference junction error
as well.
• Accuracies are listed as either 24-hour, 90-day, or 1-year
specifications. This refers to the length of time since the
instrument’s last calibration. Use the specification that
matches your calibration cycle. The 24-hour specifications are useful for determining short-term relative
performance.
Example 1: Basic dcV accuracy
When the 34970A/34972A is used outside of its 18 °C –
28 °C temperature range, there are additional temperature
drift errors to consider. Assume the same conditions in
Example 1, but at a 35 °C operating temperature.
The basic accuracy is again:
0.0035% of reading + 0.0005% of range = 365 µV.
Now, multiply the 10 V temperature coefficient from the
following page by the number of degrees outside of
operating range for additional error:
(0.0005% reading + 0.0001% range)
/ °C x (35 °C - 28 °C) =
(0.0005% reading + 0.0001% range)
/ °C x 7 °C =
0.0035% reading + 0.0007% range = 385 µV
Total error is then:
365 µV + 385 µV = 750 µV or 0.008%
Example 3: Thermocouple measurement accuracy
Calculating the total thermocouple reading error is easy
with the 34970A/34972A—just add the listed measurement
accuracy to the accuracy of your transducer. Switching,
conversion, and reference junction errors are already
included in the measurement specification.
Calculate the accuracy of the following measurement:
9 V dc input
10 V dc range
1-year accuracy specifications
Normal operating temperature (18 °C – 28 °C)
From the following page, the 1-year accuracy is:
0.0035% of reading + 0.0005% of range
Which translates into:
(0.0035/100 x 9 V)+
(0.0005/100 x 10 V) = 365 µV
For a total accuracy of:
365 µV / 9 V = 0.0041%
For this example, assume a J-type thermocouple input
reading 150° C.
From the following page, total error is:
Thermocouple probe accuracy + 1.0 °C
The probe vendor specifies accuracy of 1.1 °C
or 0.4%, whichever is greater.
Total error is then:
1.0ºC + 1.1ºC = 2.1ºC total, or 1.4%
Example 4: acV accuracy
The acV function measures the true RMS value of the input
waveform, regardless of waveshape. Listed accuracies
assume a sinewave input. To adjust accuracies for nonsinusoids, use the listed crest factor adder.
For this example, assume a ± 1 V square wave input with
50% duty cycle and a 1 kHz frequency.
Accuracy for 1 V, 1 kHz sinusoid is:
0.06% reading + 0.04% range
A 50% duty cycle squarewave has a crest factor of
Peak value / RMS value = 1 V / 1 V = 1
From crest factor table, add:
0.05% of reading
The total accuracy is:
0.11% of reading + 0.04% of range = 1.5 mV or 0.15%

Modules specifi cations
The Agilent 34970A/34972A accuracy specifications already
include the switching offset and reference junction errors
shown below. These errors are listed separately for determining system error with external measurement devices.
Up to three modules, in any combination, can be inserted
into a single mainframe. The 34970A/34972A’s internal
DMM connections are accessible only through the 34901A,
34902A, and 34908A low-frequency multiplexers.
On-module screw terminals accept wire sizes from
16 gage to 22 gage. Twenty-gage wire is recommended for
high channel count applications. The 34905A and 34906A
RF Multiplexers use SMB connectors. A standard set of
(10) BNC-to-SMB adapter cables is provided with each
RF module for convenient BNC connections.

Choose between the broad functionality of the 34901A, the
high speed scanning of the 34902A, or the single-ended
density of the 34908A. These three modules are the only
way to connect to the 34970A/34972A internal DMM. They
can be used to scan with external instruments as well.
All multiplexer modules employ break-before-make
scanning, ensuring only one closed channel (or channel
pair) at a time. Multiple channel closures are allowed on
the 34901A and 34902A modules when not configured
for scanning.
The 34908A does not allow multiple channel closures
at any time.

The Agilent 34901A is the most
versatile multiplexer for general
purpose scanning. It combines
dense, multifunction switching with
60-channel/second scan rates to
address a broad spectrum of data
acquisition applications.

Multifunction Module
• 16 bits of digital input and output
• 100 kHz totalizer input
• Two ± 12 V analog outputs
The Agilent 34907A allows great flexibility for a variety
of sense and control applications. It combines two 8-bit
ports of digital input and output, a 100 kHz gated totalizer,
and two ± 12 V analog outputs—all on a single earthreferenced module. The digital inputs and totalizer input
may be included in a scan. Alarm limits for the digital and
event counter inputs are evaluated continuously, capturing
and logging alarm conditions even between scans.
Digital input/ouput
Use the digital outputs with an external power supply to
control microwave switches and attenuators, solenoids,
power relays, indicators, and more. Use the digital inputs
to sense limit switch and digital bus status. There are no
complex handshake modes; reads and writes are initiated
either from the front panel or the bus.
