Experimentation and Laboratory-Oriented Studies
The Digilent Analog Discovery 2™ is a multi-function instrument that allows users to measure, visualize, generate, record, and control mixed signal circuits of all kinds. This instrument offers many advantages to students, including portability, durability, and a wide range of tools. Since the user's computer acts as user input and display for the Analog Discovery system, collection and recording of measurement data is also more convenient than with many traditional benchtop configurations.
In this study, the use of Analog Discovery in an Introductory Electrical Circuits Laboratory is investigated as the primary tool for measurement and signal generation. Data is collected on student level of understanding, comfort, and successful use of the tool through a comprehensive survey. The goal of the study is to compare Analog Discovery device with benchtop instruments for signal measurement and generation. To this end, data is also collected on student level of understanding, comfort, and successful use of benchtop instruments with similar functionality, including an Agilent oscilloscope and a signal generator. Primary results suggest that students find Analog Discovery easier to use and more convenient in terms of data collection.
This paper provides a quantitative summary of student feedback on use of benchtop instruments as well as Analog Discovery, in an Introductory Electrical Circuits Laboratory. The advantages of Analog Discovery including portability and cost-efficiency, combined with students’ positive feedback, makes it a suitable tool as a replacement or a companion to benchtop devices for many signal generation and measurement applications.
