The equipment is completing a modernization of the two-quarter Electronic Design class offered by the Physics Department. A third one-quarter class in computer interfacing is being developed. It will involve students in using personal computers to control temperature, and to measure the temperature dependent optical transmission of a simple Fabry- Perot etalon. They are using a real-time multitasking UNIX- like operating system, the C programming language, analog to digital and digital to analog converters, and rudiments of feedback control theory.
