It consists of two DC sources that are manually adjustable or digitally programmable in the −25 V to +25 V range, and two 4½ digit DVMs with LED displays for measuring the output voltage or load current.

The manual advises that a PI-952 Bidirectional Instrument Coupler is needed for interfacing to GPIB.
