I. Introduction

This work presents a novel approach in the implementation of a remote laboratory for an electronic experiment using LabVIEW’s remote panel technology. In the past, a number of remote labs have been tried and tested 1,2,3,4 . However, a very limited number of electronic experiments have been attempted. To our knowledge, with the exception of some simple experiments related to basic circuit analysis 5 , there is no work presented on remote experiments involving advanced electronic laboratory assignments.

This paper describes a typical electronic experiment, which can be monitored and controlled remotely. The experiment selected is a common-emitter (C-E) type bipolar junction transistor (BJT) amplifier. It is one of the electronic labs taken by most electrical engineering students typically in their junior year. With an adequate provision of GPIB- compatible instruments, the proposed prototype can be applied to virtually any advanced electronics laboratory activity.

With the server computer and experimental set up located in separate project room, the experiment was tested on a network of computers at a remote electronic laboratory. In addition, it was also tested outside the school network, such as in a home setting and at a remote university. Currently, LabVIEW comes with only one license by default. Therefore, only one client computer can monitor and run it at any time. Additional licenses such as 5, 20, or 50 can be purchased from National Instruments (the company that developed LabVIEW), which will allow multiple clients to view the experiment simultaneously.

II. Brief Theoretical Background

The primary purpose of this experiment is to demonstrate to the students that a small voltage signal (46mV rms ) can be amplified using a properly biased BJT transistor. Also, the students will learn how changes in emitter resistor ( RE ) value affect the output voltage and
