Price and performance beyond compare
Go ahead and compare the Agilent Technologies 34970A Data Acquisition/Switch Unit 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, and ease of use of the 34970A— even in systems costing three to five times as much.
How did we manage to pack so much performance into such a low-cost instrument? We borrowed tech­nology developed for our top-of-the-line products and put it into a package that cuts assembly time, incorporates custom ICs to reduce parts count, and simplifies production testing. That means it costs us less to make. The results? You spend less with­out sacrificing quality or performance.
What can you expect from a data acquisition system that’s this affordable?
Measurements you can trust
We took the measurement engine from our best­selling benchtop DMM and embedded it inside a 3-slot cardcage. 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 features 61/2 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.
Powerful flexibility to get your job done
Whether you need to measure temperature, ac/dc volts, resistance, frequency, or current, the 34970A 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.
Custom configurations that grow with you
Three module slots and eight switch/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.
Unequaled ease of use
From the simplified configuration procedures, to the self-guiding front panel interface, we put in extra time and energy to save yours. Simple things like on-module screw-terminal connectors, built-in thermocouple reference junctions, well­organized user documentation full of examples and hints, and a standard Getting Started kit that will have you making measurements 15 minutes out of the box all add up to increased productivity, whether you use the instrument every day or only now and then.
Free software to save you time and money
Now you don’t have to spend your valuable time writing or configuring software. Agilent BenchLink Data Logger II software gives you a familiar Microsoft Windows® interface for test configura­tion and real-time data display and analysis. Even better, the data logging application is included with every standard Agilent 34970A.

The Agilent 34970A offers unequaled versatility for your data acquisition applications
In the past, you had to make a choice. On the one hand, you could choose the simple operation and low cost of a data logger. On the other hand, you had the flexibility and higher performance of a modular data acquisition system. The Agilent 34970A Data Acquisition/Switch Unit gives you the best of both worlds: a simple user interface with low per-channel cost, modular flexibility, and impressive measurement performance.
Whether you’re an R&D engineer working on char­acterizing your latest design, or a manufacturing engineer building a test system or troubleshooting a process, the 34970A Data Acquisition/Switch Unit offers the best combination of price and meas­urement performance.
It’s a data logger:
Configured with a 20-channel relay multiplexer, the 34970A becomes a powerful, low-cost data logger for simple characterization applications— one that’s quick to set up and easy to run. For more information on using the 34970A for data logging applications, see page 6.
It’s a data acquisition front-end:
The 34970A is an automated test system with excellent measurement performance—it’s got the accuracy, resolution, and speed you need. See page 8 for application information.
It’s a switch system:
Order the mainframe without the internal DMM and you’ve got an even lower cost, high-quality signal routing solution. See page 10 for details.

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 irregularities. Example applica­tions include environmental chamber monitoring, component inspection, benchtop testing, process troubleshooting, and temperature profiling.
The Agilent 34970A 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 and ruggedized features make it perfect for portable applications, and its small footprint makes it ideal for cramped benchtop testing. Standard GPIB (IEEE 488) and RS-232 interfaces let you pro­gram the instrument if you wish to automate tests.
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 offers 61/2 digits of resolution and 0.004% basic 1-year dcV accuracy.
Simplify your data gathering with Agilent BenchLink Data Logger II software
Do you want PC-based data logging capability, but don’t want to spend hours programming? The BenchLink Data Logger II 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 displaying 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 II to easily move data to other applications for further analysis, or for inclusion in your presentations and reports.
And the 34970A 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 compares each reading to its limits and flags any out-of-range 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.
Scanning made simple
The 34970A 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’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.
Monitor any input
A special display mode monitors a selected input channel, continuously updating the display with new readings—even during a scan. It’s great for keeping an eye on a key input, or for troubleshoot­ing your system before a test.
Nonvolatile memory 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 to collect data at a remote location for later upload­ing to a PC. And because the nonvolatile memory also holds your system configuration, if you lose power in the middle of a test, the 34970A resumes scanning when power is returned.

A powerful, flexible data acquisition system for automated test
The 34970A 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 6
1
/2 -digit DMM brings the power and performance of a world-class stand-alone DMM to the 34970A, 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 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’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 11) 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 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
• 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

Low-cost, high-quality switching for automated test
If you don’t need the built-in measurement capability of the 34970A, save money by ordering it without the DMM. What you end up with is the lowest-cost switch unit on the market. It’s an ideal solution for routing test signals to and from your DUT and assorted instruments, including external DMMs, scopes, counters, and power supplies. Plus, you can add the DMM later if your needs change.
The functionality you need
We put a lot of thought into defining and designing the modules for the 34970A in order to cover a broad spectrum of switching and signal routing requirements with fewer modules. The result? Simplified ordering and easier configuration.
And while we were at it, we improved performance and density. The 34970A modules can switch from microvolts to 300 volts, dc to 2 GHz, and with den­sities as high as 120 single-ended channels or 96 matrix crosspoints per frame. Plus, simple control capabilities like analog outputs, open collector digi­tal outputs, and isolated Form-C relays for control­ling higher-powered devices are available.
Easy scanning
The 34970A can easily scan with external instru­ments. It builds a scan list that includes all enabled low-frequency multiplexer inputs. Scans are con­trolled with the external “channel advance” input, or with the front panel “Step” key.

Customize your Agilent 34970A 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.
Modules for the 34970A are designed to make your testing easier, faster, and more reliable. Here’s how:
Higher throughput
Our unique architecture incorporates a high­performance microprocessor on each module, off­loading the mainframe processor and minimizing backplane communications for faster throughput.
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
On-module screw-terminal connectors make wiring more convenient. Built-in strain-relief cable routing and cable tie points keep your wiring secure and safe from accidental tugs and pulls. An internal analog bus routes signals from any of the low-frequency multiplexers directly to the internal DMM, without the need for external connections.

Agilent Quality
We know you can’t afford instrument downtime due to hardware failures and unscheduled mainte­nance. That’s why our engineers designed reliability into the 34970A: A rugged enclosure, state-of-the­art surface mount construction throughout, reduced parts counts, and rigorous and thorough testing on all aspects of the product.
Take the guesswork out of relay maintenance
The 34970A uses our proprietary relay mainte­nance system to help you to predict relay end-of­life and avoid costly production-line downtime. It automatically counts every individual switch closure and stores it in nonvolatile memory on each module. You can query the total number of cycles on any individual channel so you can schedule maintenance and avoid erratic end-of­life failures.

Spec Interpretation Guide
The following pages list the technical specifications for the Agilent 34970A 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 (1V, 10V, etc.)—not the full scale value (1.2V, 12V, 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
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) = 365µV
For a total accuracy of:
365 µV / 9 V = 0.0041%
EXAMPLE 2: Extreme operating temperature
When the 34970A 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—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.
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 + 1.1 ºC = 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 non-sinusoids, 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%
[1] Specifications are for 1 hr warm-up and 61/2 digits, Slow ac filter [2] Relative to calibration standards [3] 20% over range on all ranges except 300 Vdc and ac ranges and 1 Adc and ac
current ranges
[4] For sinewave input > 5% of range. For inputs from 1% to 5% of range and

Multiplexer Selection Guide
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 internal DMM. They can be used to scan with external instruments as well.
All multiplexer modules employ break-before­make 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.
34901A
20-Channel General-Purpose Multiplexer
• 60 ch/s scanning
• Two- and four-wire scanning
• Built-in thermocouple reference junction
• 300 V switching
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.
Two- and four-wire channels can be mixed on the same module. Two additional fused inputs (22 channels total) route up to 1A of current to the internal DMM, allowing ac and dc current measurements without the need for external shunt resistors.

It com­bines two 8-bit ports of digital input and output, a 100 kHz gated totalizer, and two ±12V analog out­puts—all on a single earth-referenced 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.
Digital Input/Output
Port 1, 2 8 bit, input or output, nonisolated Vin(L) < 0.8V (TTL) Vin(H) > 2.0V (TTL) Vout(L) < 0.8V @ Iout = - 400 mA Vout(H) > 2.4V @ Iout = 1 mA Vin(H) max < 42V with external open drain pull-up Alarming Maskable pattern match or state change
Speed 4 ms (max) alarm sampling Latency 5 ms (typical) to 34970A alarm output
Read/Write Speed 95/s
Totalize Input
Count events from devices like photo interrupters, limit switches, and Hall-effect sensors.
It keeps an updated total which can be read via the front panel or programmatically at any time. With 26 bits of resolution, it can count events at full speed for nearly 11 minutes without an overflow.
Totalize Input
Max Count 226- 1 Totalize Input 100 kHz (max) Rising or falling edge,
programmable Signal level 1 Vp-p (min) 42 Vpk (max) Threshold 0V or TTL, jumper selectable Gate Input TTL-Hi, TTL-Lo, or none Count Reset Manual or Read + Reset Read Speed 85/s
Analog Output
Use the two electronically calibrated analog out­puts to source bias voltages to your device under test, to control your analog programmable power supplies, or use the outputs as setpoints for your control systems. The outputs are programmed directly in volts, either from the front panel or from the bus.
