Agilent/Keysight 6237B DC Power Supply

The Agilent/Keysight 6237B is a triple-output DC power supply engineered for electronic testing and IC circuit development. It delivers two tracking ±20 V outputs and one independent +18 V output, each with constant voltage/current limiting protection. The front panel features logically arranged controls, analog meters, and binding posts for straightforward setup and operation.

All three outputs share a common terminal isolated from chassis ground, permitting flexible grounding configurations.
