DAQ973A Data Acquisition System Mainframe

DAQ973A is a mainframe for housing DAQM plug-in modules. Interface with the DAQ using Keysight BenchVue DAQ software or use the intuitive graphical front panel with task-oriented, self-guiding menus (similar to DAQ970A). However, the DAQ973A adds GPIB capability to the popular DAQ970A. It is the perfect replacement and upgrade to the 34970A if you require a GPIB interface.

• Measures very low current ranges (1 µA DC and 100 µA AC) and higher resistance (1000 MΩ)

• New auto-calibration compensates for internal drifts caused by time / temperature changes

• 34970A/34972A compatible program and configuration

• Updated modules have improved switching speeds and accuracies

• USB flash drive support to copy/log data in standalone applications

• LAN/LXI, USB, and GPIB for easy connectivity to your PC

• BenchVue DAQ application with enhanced time/frequency domain measurement included

• Three-year warranty

Built-in Signal Conditioning to Get Your Job Done

Whether you need to measure temperature, ac/dc volts, resistance, frequency, or current, the DAQ970A can handle it. The internal autoranging DMM directly measures 12 different functions, eliminating the need for expensive external signal conditioning. And its 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.

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. Keysight uses 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.

Simplify Your Data Gathering and Analysis with Keysight's BenchVue

BenchVue software offers an intuitive interface for test configuration, real-time data display, and analysis. It allows quick setup and measurements, data export, and real-time logging with various display types. The software supports many Keysight instruments, providing a single interface for popular devices. Its familiar spreadsheet environment simplifies test configuration and control, enabling multiple graphics setups like strip charts, histograms, bar and scatter charts, and individual channel results for inclusion in presentations and reports.

Customize your Keysight DAQ970A with Plug-in Modules (sold separately)

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 DAQ970A 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.

Unequaled Ease of Use

Simple things like built-in thermocouple reference junctions, well-organized user documentation full of examples and hints, all add up to increased productivity, whether you use the instrument every day or only now and then.

In addition, on-module screw-terminal connectors make wiring more convenient. Built-in strain relief cable routing and cable tie points keep your wiring secure. An internal analog bus route signals from any of the low-frequency multiplexers directly to the internal DMM without the need for external connections.
