摘要：

The construction and electrical characteristic of a programmable, microprocessor-controlled current source are described. The source is suitable for supplying superconducting nuclear magnetic resonance magnets as well as for general applications. The source has a bipolar output with maximum output current +/- 5 A/+/- 10 V with stability better than 5 x 10(-5) and the current step 160-mu-A. The rate of excitation of the output current may be varied from 2 ms to 9.999 s per step, with 1 ms resolution. The source is fully programmable via HP-IB bus.
