The 6256B is a single-output DC power supply that is intended for ATE or other integrated applications. As such, its main output (and optional remote sensing signals) is on a rear-panel screw terminal barrier strip. It has front-panel banana jacks for voltage monitoring. They can be used for output, but are only rated to provide 3A.

Many options were available for this power supply, mostly pertaining to the voltage and current controls and the input voltage.
