DAQ973A adds GPIB capability to the popular DAQ970A. It is the perfect replacement and upgrade to the 34970A if you require a GPIB interface.

Sample More Signals, Faster
The DAQ973A is Keysight's next-generation data acquisition (DAQ) system with a 3-slot mainframe and your choice of 8 plug-in modules. Interface with the DAQ using optional Keysight BenchVue DAQ software, the intuitive graphical front panel with task oriented, self-guiding menus, or a web browser.

Measurements You Can Trust
Keysight took the measurement engine from their best-selling benchtop DMM and embedded it inside a 3-slot mainframe. You get the benefit of proven Keysight measurement performance, universal inputs with built-in signal conditioning, and modular flexibility, all in a low-cost, compact data acquisition package. The DAQ973A features 6-1/2 digits (22 bits) of resolution, 0.004% basic dcV accuracy, and ultra-low reading noise. Combine that with scan rates of up to 450 channels/sec, and you’ve got the speed and accuracy you need to get the job done right the first time.

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.

Built-in Signal Conditioning to Get Your Job Done
Whether you need to measure temperature, ac/dc volts, resistance, frequency, or current, the DAQ973A can handle it. The internal autoranging DMM directly measures 12 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.

Simplify your data gathering and analysis with Keysight BenchVue DAQ software
Keysight's BenchVue DAQ Control and Analysis app option is available for use with the DAQ973A. BenchVue gives you an intuitive interface for test configuration and real-time data display and analysis. Setup and make measurements quickly, export data or log and view real-time measurements with a variety of display types to interpret your data faster. BenchVue Software also supports many other Keysight instruments giving you a single interface for Keysight's most popular instruments.

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 BenchVue DAQ to easily move data to other applications for further analysis, or for inclusion in your presentations and reports.

Customize your Keysight DAQ973A 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.

Data Acquisition/Switch Unit Modules for the DAQ973A Data Acquisition System:
Choose between the broad functionality of the DAQM901A, the high speed scanning of the DAQM902A, or the DAQM900A solid-state module the single-ended density of the DAQ908A. All multiplexer modules employ break-before-make scanning, ensuring only one closed channel (or channel pair) at a time.
