34972A LXI data acquisition / data logger switch mainframe with built-in 6,5-digit DMM

The Keysight 34972A data acquisition / data logger switch consists of a three-slot mainframe with a built-in 6 1/2-digit digital multimeter. You can configure each channel 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. It  is an LXI version of the 34970A. It replaces the GPIB and RS-232 interfaces with modern connectivity for a direct connection to your PC or Laptop.
