    The 34972A LXI Data Acquisition/Switch Unit is an LXI version of the 34970A. It replaces the GPIB and RS-232 interfaces with modern connectivity - LAN and USB - for a direct connection to your PC or Laptop.

    The New Keysight 34972A Data Acquisition Switch Unit consist of a 3-slot mainframe with a built-in 6.5 digit DMM and 8 different switch & control modules. This product features built-in LAN and USB interfaces so you can easily connects to a PC or laptop without needing to purchase additional IO cards or converter interfaces. The intuitive graphical Web interface offers easy remote control over the network with per channel measurement configuration, data logging and data monitoring achieved through a standard Web browser or the BenchLink Data Logger software. With the 34972A, there is no computer required for field applications. Use a USB flash drive to upload data logging configurations into the 34972A and to transfer large data sets back to the computer. Simply connect the USB stick to your PC when you return for data analysis.

    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.
