Introduction

Your ECE laboratory experience at UNC Charlotte has been designed to provide you with the basic laboratory skills needed in your engineering profession. The ability to build and evaluate electrical and electronics equipment is essential for the majority of jobs in Electrical and Computer Engineering. Your laboratory assignments will require a methodical approach to the collection and analysis of data and will emphasize the appropriate presentation of your results.

In order to gain the most from your laboratory experience you must study each experiment and answer the pre-lab questions in advance of the laboratory meeting.  At times this may require that you investigate subjects with which you have limited familiarity.  Having not covered the material in lecture is no excuse for not making an effort to solve the problems.  You are welcome to visit my office at any time to obtain help and reference material.  Your TA will also provide you with additional instruction and reference material as you may require.                                                                                                       

We hope your laboratory experience will be a valuable part of your engineering education and we will continually strive to improve our presentation.  If you have questions or concerns that you think we should be aware of please do not hesitate to bring them to our attention.

ECE Lab Schedule, Fall 2008

ECGR 2155 Students:  You will need a set of hand tools and other items that will be used for ECGR 2155 and all future lab courses.  A complete "Lab Kit" may be purchased from the department by following this procedure:  Purchase Lab Kit.  The Lab Kit price is $175.  You must have the tools in order to do the lab experiments, but you are not required to purchase them from the university.  Here is a list of the Lab Kit Contents for those who choose to provide their own tools.

ECGR 2255 Students:  You will be using Mentor Graphics on Sun or Linux workstations.  Mr. Karwal will conduct MG workshops prior to the first official class meeting on September 10th for those who are unfamiliar with the software or operating systems.

Please Note:  Fall 2008 ECE labs will begin the week of September 8th.  Laboratory classes do not meet during the first week of the term, or in any week that the university is open for fewer than five full days.  Labs will not be held Aug 25-29, Sept 1-5, Oct 13-17, Nov 24-28, or Dec 8-9.

Laboratory final examinations will be administered the week of December 1st - 5th.
