Section 1. Features and Specifications
Description
The internal GPIB-M interface card allows you to operate your power supply from
a computer controller via the IEEE-488 communications bus.
The GPIB-M interface allows complete remote programming of your power supply,
including status reporting, settings query, and service request generation with
user-designated conditions. Both the voltage and current output are precisely
programmed directly in volts and amps with 16-bit resolution. Additionally, the
16-bit readbacks measure the actual power supply output. The programming
command set is easy to use and includes software calibration commands. The
interface card comes with several protection features such as programmable over
and under voltage protection, and soft limits.
Multichannel addressing via CANbus allows up to 50 power supplies to be
controlled from one GPIB address. This manual covers operation of both the
GPIB-M and CAN-only interface cards.
