NEW LAB KIT PURCHASE PROCEDURE
In an effort to simplify the purchase process, while providing a quality product at lower cost, a new procedure for purchasing lab kits will be adopted beginning in Spring 2010. Students will order lab kits directly from the vendor's website. Lab kits will no longer be available through the ECE Department. BE SURE TO PLACE ORDERS WELL BEFORE THE START OF CLASSES TO ASSURE SUFFICIENT TIME FOR ORDER PROCESSING AND SHIPPING. See the "Student-Supplied Materials" section below for details.
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. Although a diligent effort to synchronize experiments with lecture topics has been made, you may be required at times to perform experiments on topics that have not been fully covered in class. It is therefore important to be well prepared for each lab session by starting the pre-lab exercise early and asking questions as necessary. See your TA or visit my office for help or reference materials if you are having difficulty understanding a pre-lab exercise or experimental procedure.
We hope your laboratory experience will be a valuable part of your engineering education. Questions, concerns and suggestions are always welcome.
Student-Supplied Materials
Text books are not required for laboratory courses. Instead, students must provide hand tools, test leads, breadboards, and other items that are used to set-up and perform experiments. One set of tools is required for each lab working group – usually two students. A complete "Lab Kit" may be purchased online:
Lab Kit Purchase
Lab kits are available from Electronix Express through their UNC Charlotte website at http://elexp.com/unc.htm. Two pre-packaged kits are available: 1) Standard -- $132.00, and 2) Deluxe -- $217.00. To view the contents of a kit, click "More Info" beside the line item on the Electronix Express web page. Individual kit items are described in the Electronix Express online catalog http://www.elexp.com/. A sample kit is available for examination in Mr. Hill's office at 233 Woodward.
The same tools are required for every lab course, and tools need to be purchased only once.

Teaching Assistants, Fall 2009
ECE Lab Schedule, Fall 2009
Laboratory Classes are not scheduled for the first week of the term, or during any week that the university is open for fewer than five full days. (When unscheduled university closings occur, e.g., for inclement weather or emergencies, lab classes will meet at their regular times for the remainder of the week. Lab TA's will arrange make-up sessions for labs canceled due to the unscheduled university closing. Check the UNC Charlotte website for emergency closings. If the university is closed, lab classes are cancelled.)
Fall 2009 ECE labs will begin the week of August 31st. Fall 2009 labs will not be held August 24-28, September 7-11, October 12-16, November 23-27, or December 7- 9... with the following exceptions:
ECGR 2155 Students: Tutorial sessions will be held at your regular class meeting times during the week of August 24-28 to familiarize you with the operation of essential laboratory test equipment (oscilloscopes, signal generators, meters, etc.).
ECGR 2255 Students: You will be using Mentor Graphics on Sun or Linux workstations. Your TA will conduct MG workshops prior to the first official class meeting for those who are unfamiliar with the software or operating systems.
Pre-Lab exercises must be completed and turned in at the beginning of each lab class. If you think that you will need to reference pre-lab information to perform experiments or to do post-lab work, make copies. The pre-lab for Experiment #1 is due the week of August 31st at your regular class meeting time.
Fall 2009 laboratory comprehensive examinations will be administered the week of November 30th.
