Agilent/Keysight 59501B D/A CONVERTER

The Agilent/Keysight 59501B is an isolated digital-to-analog converter and power supply programmer that bridges HP-IB control systems to analog-capable power supplies lacking native bus interface. It enables remote, digitally controlled voltage and current programming of compatible instruments and functions as a standalone low-level DC signal source.
