Notes:
In order to obtain low uncertainty levels in computer-controlled electrical precision measurements, the controlling system must not interfere with the measurement system. The optical interface described here provides the two systems with an insulation resistance higher than 1014 Ω using two optical fibers, which also allow the systems to be remotely located. The interface treats two dc voltage signals: one of them is used to drive the measuring system, and the other is the result of the measurement and can be read with a relative accuracy of 1×10−4. The interface can be used to automatically drive dc resistance bridges and will be applied to a cryogenic setup having a superconducting quantum interference device as a detector. © 1995 American Institute of Physics.
