The Keysight 34902A module for the 34970A/34972A Data Acquisition/Switch Unit employs reed relays to achieve scan rates up to 250 channels-per-second. Use this module for high-throughput automated test applications as well as high-speed data logging and monitoring tasks.
Sixteen two-wire inputs switch up to 300 V. Two-and four-wire channels may be mixed on the same module. User provided shunt resistors are required for current measurements.
