NEW: Beginning Spring 2011, lab reports will be submitted and graded online using Moodle.  Please check Moodle for your section schedule.

Safety Glasses must be worn in labs 203, 204, 231 & 232 when cutting, soldering, or energizing power circuits

Students must read and follow these Lab Safety Rules  


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 -- Lab kits

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 - and may be shared, although most students prefer to have their own kits.  The same tools are required for all lab courses, so a one-time purchase covers most student-supplied materials needed for ECGR 2155, 2156, 3155, 3156 and 2255.

Lab kits may be purchased online from Electronix Express through their UNC Charlotte website at . Two pre-packaged kits are available: Standard, and Deluxe. The standard kit contains everything that you will need for in-class experiments.  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 .  A sample kit is available for examination in Mr. Hill's office at 233 Woodward.


Academic Integrity

Students work together in the laboratory to build circuits and measure data.  Except for discussion and the sharing of data among lab partners, collaboration ends when the lab session is over.  Students must work independently to write their own pre-lab exercises and reports.  There must be no copying of student-generated text, tables, charts or graphs.  Use of text copied from internet sources, e.g., Wikipedia is strictly forbidden.  Raw data aside, any duplicate work submitted will be viewed as cheating, and will result in disciplinary action according to university policy  The penalty for a first offense can range from a formal warning to an F for the course.  Regardless of the penalty imposed, a record of the offense will be kept for eight years in the Office of the Dean of Students.

Religious Holidays - New University Policy

"UNC Charlotte provides reasonable accommodations, including a minimum of two excused absences each academic year, for religious observances required by a student's religious practice or belief. It is the obligation of students to provide faculty with reasonable notice of the dates of religious observances on which they will be absent by submitting a Request for Religious Accommodation Form to their instructor prior to the census date for enrollment for a given semester.  The census date for each semester (typically the tenth day of instruction) can be found in UNC Charlotte's academic calendar."  The full text of this policy is available at .

ECE Lab Schedule, Spring 2011

Spring 2011 ECE labs (experiments) will begin the week of January 24th; Special tutorial sessions will be held for ECGR 2155 sections the week of January 10th.

Spring 2011 lab sections will not meet:

  • January 10-21 (Except for ECGR 2155; See note, below) 
  • March 7-11
  • April 18-22
  • May 2-3

Note: Mandatory tutorial sessions will be held for all ECGR 2155 sections at regular class meeting times during the week of January 10th to familiarize students with the operation of essential laboratory test equipment (oscilloscopes, signal generators, meters, etc.).  Failure to attend will result in a 10% reduction of the first lab report grade.  RESCHEDULED.  SEE MOODLE PAGE FOR YOUR LAB SECTION.

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 January 24th at your regular class meeting time.

Spring 2011 laboratory comprehensive examinations will be administered the week of April 25th.

EMERGENCY CLOSINGS:  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.
