The Keysight 34702A is a Digital Multimeter module designed for integration into the Keysight 34970A and 34972A Data Acquisition/Switch Units. It delivers essential DC and AC voltage, current, and resistance measurements in automated test and data logging environments. The module supports both 2-wire and 4-wire resistance configurations, with low-current measurement capability down to 1 µA and pA resolution. While the host 34970A and 34972A systems are legacy products, Keysight continues to support the 34702A and compatible modules across their standard support lifecycle.
