ELECTRONICS WORKBENCH THE ELECTRONICS LAB IN A COMPUTER

Mohammad H. Ahmadian Electronics Engineering Technology Eastern New Mexico University Portales, NM 88130

Abstract

The electronics workbench is an electronics lab in a computer. This package provides students with the ability to study a circuit behavior and check the results as they are displayed on the multimeter, oscilloscope, Bode plotter, and logic analyzer. The analog, digital, and mixed-mode features make this package a practical tool that may be incorporated as part of the electronics laboratory assignments.

Introduction

Electronics, perhaps more than any other field of technology has enjoyed an explosive development in the last four decades. Electronics is a fascinating field because it provides the opportunity to be creative and at the same time solve problems.

In the electronics programs every effort has been made to have the students develop a good intuitive feel for circuit operation, while at the same time showing him or her how to analyze expected circuit performance using the appropriate mathematical relationship. This permits the students to systematically analyze, troubleshoot, or even design various circuits in an orderly and effective manner.

Most electronics courses taught these days are organized around what is called lecture-and-lab structure. This structure typically uses lectures on subject matter and is supplemented by laboratory experience. In addition to familiarizing the students with the type of equipment that he or she will use in industry, the experiments are also designed to verify or prove out the theoretical concepts discussed in the classroom. Very often this experimenting in the lab is the only hands-on experience the electronics students are likely to get. Students do not ordinarily build permanent, working prototype projects.

If the laboratory experiments are not generating the expected results, very often the whole experiment needs to be repeated. The unexpected results could be due to faulty components, incorrect design specifications, or improper connections. Nonetheless, implementing a circuit in the lab with undesired output might be time consuming. However, having an electronics simulator will enable the students as well as the instructor to analyze the performance of a circuit prior to implementing the actual hardware components.
