Agilent/Keysight 66001A DC Power Supply

The Agilent/Keysight 66001A is a detachable keyboard controller for the 66000 Modular Power System (MPS), enabling manual operation and program development without requiring a computer. It interfaces with the 66000A mainframe - a 4U, 8-slot chassis - which accommodates up to eight interchangeable DC power modules totaling 1200 W. The 66001A provides direct access to voltage and current programming, electronic calibration, and system configuration while supporting GPIB remote control for automated test sequences.

• System Power: Up to 1200 W across eight modules; individual modules rated to 150 W

Key Features

• Electronic voltage and current programming via GPIB using SCPI commands


• Electronic calibration capability from keyboard or GPIB interface


• User-definable power-on state configuration


• Five non-volatile store-recall states per output


• LIST Mode and advanced triggering for optimized test sequencing


• Output sequencing with up to 20 downloadable parameter sets per output


• Programmable Over-Voltage Protection (OVP) and Over-Current Protection (OCP)

Compatibility & Integration The 66001A keyboard works exclusively within the 66000 MPS architecture. The system supports serial linking of multiple mainframes, enabling up to 16 outputs under single GPIB address control. Compatible DC power modules include the 6640, 6650, 6670, 6680, and 6030 series, offering power ranges from 150 W to 5000 W. Module swapping allows rapid system reconfiguration for diverse test requirements.
