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 measurement 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 61/2 digits of resolution and 0.004% basic 1-year dcV accuracy. 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. Scanning made simple The 34970A/34972A automatically builds a scan list that includes all configured inputs (even digital inputs from the Keysight 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. 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 flash 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 -- Measurements include dc volts, ac volts, thermocouple, thermistor and RTD temperature measurements, 2- and 4-wire Ohms, dc current, ac current, frequency, and period -- 61/2 digits (22 bits) of resolution with 0.004% basic 1-year dcV accuracy -- 50 k reading nonvolatile memory including timestamp -- Scaling and alarms available on each channel -- Full-featured front panel for stand-alone configuration, troubleshooting, and data viewing -- BenchLink Data Logger 3 software for configuration and data analysis -- Nonvolatile storage for five complete instrument states -- Built-in LAN or USB interfaces to support remote data logging applications (34972A only) 9 A powerful, flexible data acquisition system for automated test The 34970A/34972A gives you the resolution, accuracy, repeatability, and speed you've come to expect from a Keysight 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 61/2 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 Keysight 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 -- 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 10 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), Keysight 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 or LAN and USB on the 34972A and SCPI programming language make integration even easier.

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/34972A 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/34972A 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. Low-cost switching system for automated testing 12 Easy scanning The 34970A/34972A 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. Connect to the company network With the 34972A's LAN interface, the instrument is easily connected to the company network to collect measurement data to a central database, remotely access the instrument's set up, or monitor measurement data from anywhere on the network. Customize your Keysight 34970A/34972A with plug-in modules More channels in less space 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/34972A are designed to make your testing easier, faster, and more reliable. Here's how: Higher throughput Our unique architecture incorporates a high-performance microprocessor on each module, off loading the mainframe processor and minimizing backplane communications for faster throughput. 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. Use the chart below to help you pinpoint the modules that meet your needs. 34970A and 34972A Keysight modules-at-a-glance selection guide Model description Type 34901A 20 ch Multiplexer + 2 current channels 34902A 16 ch Multiplexer 34903A 20 ch Actuator/GP Switch 34904A 4 x 8 Matrix 34905A Dual 4 ch RF Mux 50 34906A Dual 4 ch RF Mux 75 34907A Multifunction Module 34908A 40 ch Single-Ended Mux [1] Speed (ch/sec) Max volts Max amps Bandwidth Thermal Comments offset 2-wire armature (4-wire selectable) 60 300 V 1A 10 MHz < 3 V 2-wire reed (4-wire selectable) SPDT/form C 250 [1] 300 V 50 mA 10 MHz < 6 V 120 300 V 1A 10 MHz < 3 V 2-wire armature Common low (unterminated) Common low (unterminated) Two 8-bit digital I/O ports 26-bit event counter Two 16-bit analog outputs 120 60 300 V 42 V 1A 0.7 A 10 MHz 2 GHz < 3 V < 6 V 60 42 V 0.7 A 2 GHz < 6 V 42 V 42 V 12 V 400 mA 10 mA 100 KHz dc 1-wire armature (common low) 60 300 V 1A 10 MHz < 3 V Built-in cold junction reference 2 additional current channels (22 total) Built-in cold junction reference Page 21 21 23 1 GHz bandwidth through BNC-to-SMB adapter cable 1 GHz bandwidth through BNC-to-SMB adapter cable Open drain Selectable input threshold Max 40 mA total output per frame Built-in cold junction reference No four-wire measurements 23 24 24 25 21 Up to 250 ch/sec to internal memory.

That's why our engineers designed reliability into the 34970A/34972A: A rugged enclosure, state-of-the-art surface mount construction throughout, reduced parts counts, and rigorous and thorough testing on all aspects of the product. The 34970A/34972A uses our proprietary relay maintenance system to help you to predict relay end-of-life 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-of-life failures. 14 Spec interpretation guide Example 2: Extreme operating temperature The following pages list the technical specifications for the Keysight 34970A/34972A Data Acquisition/Switch Unit and its modules. The explanations and examples below are helpful in understanding how to interpret these specifications: 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. -- 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 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 V For a total accuracy of: 365 V / 9 V = 0.0041% The basic accuracy is again: 0.0035% of reading + 0.0005% of range = 365 V. 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 V Total error is then: 365 V + 385 V = 750 V 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. 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: 1.0C + 1.1C = 2.1C 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% 15 34970A/34972A accuracy specifications (% of reading + % of range)[1] Includes measurement error, switching error, and transducer conversion error Range [3] Frequency, etc. 24 hour [2] 23 C 1 C 90 Day 23 C 5 C 1 Year 23 C 5 C 0.0030 + 0.0035 0.0020 + 0.0006 0.0015 + 0.0004 0.0020 + 0.0006 0.0020 + 0.0020 0.0040 + 0.0040 0.0030 + 0.0007 0.0020 + 0.0005 0.0035 + 0.0006 0.0035 + 0.0030 0.0050 + 0.0040 0.0040 + 0.0007 0.0035 + 0.0005 0.0045 + 0.0006 0.0045 + 0.0030 0.0005 + 0.0005 0.0005 + 0.0001 0.0005 + 0.0001 0.0005 + 0.0001 0.0005 + 0.0003 3 Hz-5 Hz 5 Hz-10 Hz 10 Hz-20 kHz 20 kHz-50 kHz 50 kHz-100 kHz 100 kHz-300 kHz [5] 3 Hz-5 Hz 5 Hz-10 Hz 10 Hz-20 kHz 20 kHz-50 kHz 50 kHz-100 kHz 100 kHz-300 kHz [5] 1.00 + 0.03 0.35 + 0.03 0.04 + 0.03 0.10 + 0.05 0.55 + 0.08 4.00 + 0.50 1.00 + 0.05 0.35 + 0.05 0.04 + 0.05 0.10 + 0.10 0.55 + 0.20 4.00 + 1.25 1.00 + 0.04 0.35 + 0.04 0.05 + 0.04 0.11 + 0.05 0.60 + 0.08 4.00 + 0.50 1.00 + 0.08 0.35 + 0.08 0.05 + 0.08 0.11 + 0.12 0.60 + 0.20 4.00 + 1.25 1.00 + 0.04 0.35 + 0.04 0.06 + 0.04 0.12 + 0.05 0.60 + 0.08 4.00 + 0.50 1.00 + 0.08 0.35 + 0.08 0.06 + 0.08 0.12 + 0.12 0.60 + 0.20 4.00 + 1.25 0.100 + 0.004 0.035 + 0.004 0.005 + 0.004 0.011 + 0.005 0.060 + 0.008 0.20 + 0.02 0.100 + 0.008 0.035 + 0.008 0.005 + 0.008 0.011 + 0.012 0.060 + 0.020 0.20 + 0.05 1 mA current source 1 mA 100 A 10 A 5.0 A 500 nA 500 nA || 10 M 0.0030 + 0.0035 0.0020 + 0.0006 0.0020 + 0.0005 0.0020 + 0.0005 0.002 + 0.001 0.015 + 0.001 0.300 + 0.010 0.008 + 0.004 0.008 + 0.001 0.008 + 0.001 0.008 + 0.001 0.008 + 0.001 0.020 + 0.001 0.800 + 0.010 0.010 + 0.004 0.010 + 0.001 0.010 + 0.001 0.010 + 0.001 0.010 + 0.001 0.040 + 0.001 0.800 + 0.010 0.0006 + 0.0005 0.0006 + 0.0001 0.0006 + 0.0001 0.0006 + 0.0001 0.0010 + 0.0002 0.0030 + 0.0004 0.1500 + 0.0002 3 Hz-5 Hz 5 Hz-10 Hz 10 Hz-40 Hz 40 Hz-300 kHz 0.10 0.05 0.03 0.006 0.10 0.05 0.03 0.01 0.10 0.05 0.03 0.01 0.005 0.005 0.001 0.001 <0.1 V burden <0.6 V <2 V 0.005 + 0.010 0.010 + 0.004 0.050 + 0.006 0.030 + 0.020 0.030 + 0.005 0.080 + 0.010 0.050 + 0.020 0.050 + 0.005 0.100 + 0.010 0.002+ 0.0020 0.002 + 0.0005 0.005 + 0.0010 3 Hz-5 Hz 5 Hz-10 Hz 10 Hz-5 kHz 3 Hz-5 Hz 5 Hz-10 Hz 10 Hz-5 kHz 1.00 + 0.04 0.30 + 0.04 0.10 + 0.04 1.00 + 0.5 0.30 + 0.5 0.10 + 0.5 1.00 + 0.04 0.30 + 0.04 0.10 + 0.04 1.00 + 0.5 0.30 + 0.5 0.10 + 0.5 1.00 + 0.04 0.30 + 0.04 0.10 + 0.04 1.00 + 0.5 0.30 + 0.5 0.10 + 0.5 0.100 + 0.006 0.035 + 0.006 0.015 + 0.006 0.100 + 0.06 0.035 + 0.06 0.015 + 0.06 DC voltage 100.0000 mV 1.000000 V 10.00000 V 100.0000 V 300.000 V True RMS AC voltage [4] All ranges from 100.0000 mV to 100.0000 V 300.0000 V Resistance [6] 100.0000 1.000000 k 10.00000 k 100.0000 k 1.000000 M 10.00000 M 100.0000 M Frequency and period [7] 100 mV to 300 V DC current (34901A only) 10.00000 mA 100.0000 mA 1.000000 A True RMS AC current (34901A only) 10.00000 mA and [4] 1.000000 A 100.0000 mA [8] Temperature Thermocouple RTD Thermistor [1] [2] [3] [4] [5] 16 [10] Type B E J K N R S T R0 from 49 to 2.1 k 2.2 k, 5 k, 10 k 1-year accuracy [9] 1100 C to 1820 C -150 C to 1000 C -150 C to 1200 C -100 C to 1200 C -100 C to 1300 C 300 C to 1760 C 400 C to 1760 C -100 C to 400 C -200 C to 600 C -80 C to 150 C Extended range 1-year accuracy [9] 1.2 C 1.0 C 1.0 C 1.0 C 1.0 C 1.2 C 1.2 C 1.0 C 0.06 C 0.08 C Specifications are for 1 hr warm-up and 61/2 digits, Slow ac filter Relative to calibration standards 20% over range on all ranges except 300 Vdc and ac ranges and 1 Adc and ac current ranges For sinewave input > 5% of range.

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.

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 1 A of current to the internal DMM, allowing ac and dc current measurements without the need for external shunt resistors.
