describe

The Keysight 34970A data acquisition / data recorder switch unit consists of a 3 - slot host and a built - in 6 - 1 / 2 - bit digital multimeter . Each channel can be configured individually to measure one of 11 different functions , which will neither increase costs nor use complex signal conditioning accessories . You can use eight optional insert modules to build a compact data recorder , a full - function data acquisition system , or a low - cost switch unit . The most popular 34901A module has built - in thermocouple reference and 20 2 - wire channels .
