Keysight will discontinue the 34972A on June 1, 2020. The last order date of the 34972A is May 31, 2020. Keysight's new DAQ970A is backwards compatible with the 34972A. The DAQ970A improves user experience with a color LCD, internal module calibration, and faster temperature accuracy and measurement speeds. MORE INFO...
The Keysight 34972A data acquisition / data logger switch unit consists of a three-slot mainframe with a built-in 6 1/2 digit digital multimeter. Each channel can be configured independently to measure one of 11 different functions without the added cost or hassles of signal-conditioning accessories. Choose from eight optional plug-in modules to create a compact data logger, full-featured data acquisition system or low-cost switching unit. On-module screw-terminal connections eliminate the need for terminal blocks and a unique relay maintenance feature counts every closure on every switch for easy, predictable relay maintenance. Our most popular module 34901A features a built-in thermocouple reference and 20 two-wire channels.
Keysight’s BenchVue DAQ Control and Analysis app is available for use with the DAQ970A, 34970A, 34972A and 34980A. 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.
The 34972A can accept any of the 34970A plug-in modules. With a simple address change the 34972A is easily integrated into an exiting test with no wiring or hardware changes. The plug-in modules also feature on-board screw terminals and relay closure count so you can create a compact data logger, full-featured data acquisition system or low-cost switching unit that is easy to connect, configure and use on the bench, on a network or in field applications.
