This paper describes the culmination of a two-year project which had two aims: (1) development of computer-based laboratory instruments (CLIs) consisting of LabVIEW virtual- instrument programs coupled with custom external hardware; (2) integration of these CLIs into the undergraduate curriculum. Students were brought into the design process wherever possible, giving them first-hand experience with open-ended design problems. Project TUNA (Texas Universal Network Analyzer), a CLI which characterizes the frequency response (magnitude and phase) of linear networks over a frequency range of 10 Hz to 100 kHz, was designed as a class project in EENG 4409 (Electronic Circuit Analysis II) in 1999, and served as the model for this project. Project TUNA was described in a previous paper presented to the 2000 ASEE Annual Conference. A grant from the National Science Foundation (DUE-9952292) was received in April, 2000, to support further development of CLIs at the University of Texas at Tyler. An interim progress report was presented to the 2001 ASEE Annual Conference. This paper summarizes the CLIs and their use in the curriculum and describes the resources developed by this project which have been made available to other electrical engineering programs.
