We have developed a simple, low-cost, GPIB programmable precision voltage source for laboratory use with two outputs in the range[0,−5]V and[0,+5]V. The original goal was to allow the interfacing to personal computer of older high-voltage sources that can be remotely driven by an analog signal. This voltage source can be more generally used whenever a GPIB programmable low-power precision voltage source is needed. ©1997 American Institute of Physics.
