A new direction or class assistance during laboratory sessions

Experimental training for undergraduate students in electric and electronic engineering courses must take advantage of emerging technologies. PC-based measurement systems, as well as, virtual instruments are very useful for beginners, which help test theoretical knowledge, carry out useful self-training, and acquire basic hands-on experience with problems arising in real-world experimental trials. Still, training with real instruments in a laboratory can provide students the necessary experience in measurement procedures and basic expertise in the design of measurement systems. Great efforts must be made in the development of new methodologies and tools able to fit the requirements of classes involved in experimental sessions. Advanced technologies can support the development of highly featured and capable laboratory sessions. As an example, the client-server tool presented in this article represents a partial result of a step-by-step ongoing work, which includes a suitable software interface and circuits that will be used to carry out classical experiments. The system has proved to be very useful for the experimental training of undergraduates and they can use it by themselves through a user-friendly interface. Moreover, the laboratory is available for greater lengths of time and can solve the problem of the lack of an adequate number of tutors.
