The Keysight 1143A provides power and independent offset control for two Keysight 54700-series probes. The probe's offset can be controlled via a 9-pin, D-subminiature connector on the rear panel of the Keysight 1143A. Additionally, the ±50 V offset capability extends the dynamic range of the probe measurement system beyond that of many test and measurement instruments.
