ECEN 313 LABORATORY INSTRUCTIONS

The laboratory portion of this course is intended to provide experience in design, construction, testing, and simulation of many of the circuits introduced and studied in the lecture portion.

The Laboratory

The experiments are intended to be performed in the analog laboratory (rooms 428 and 430 CB). Most of the required test equipment and power supplies are available in this lab. The lab has recently changed from an open lab to a closed lab period. There are two lab sections per week: Tu. 3-5:50, and Th. 12-2:50. A TA will be available during lab time. There is some make-up time available on Friday with limited TA support.

Laboratory Rules and Procedures

Important Note: Lab groups consist of two persons. All students are expected to understand the lab concepts. Each individual will do the lab preparation and recording of results. Each individual will turn a copy of his/her notebook record in for a lab grade.

All experimental data is to be taken in conventional laboratory notebooks. This data should be taken carefully and professionally. However, notebooks are expected to be working records. It is not necessary to cut and paste the experiment instruction sheets into the lab notebooks, although a schematic may be used.

The notebook record should contain the following.

Introduction— In the introduction you should explain in your words the purpose of the lab. You might want to leave a blank page in the beginning to fill in the introduction after you have completed the lab.

Preliminary Calculations—You should provide any preliminary calculations in this section. This work should be performed prior to coming to lab.

Results— This section of the notebook should follow the lab procedure and could include the following. A thorough understanding of the material covered in the lab must be demonstrated in this section to receive a good grade.

Schematic— No lab involving circuits should ever be turned in without an accompanying schematic.

Simulation— This should include the pSpice program as well as the results of the simulation.

Measurements— This section should include both an explanation of the measurements taken as well as the actual measurements. This should be a narrative such as, “I measured the output voltage with the oscilloscope and found it was a 5 V peak signal at 1000 Hz”.

Discussion of results—Comparisons should be made between the preliminary calculations, the simulations, and the measurements. Be sure to explain any large discrepancies. Be sure to answer any questions asked in the lab.

4. Summary—This section will provide a summary of what was learned in the lab and any significant discrepancies between calculated, simulated, and measured results.

A Xerox copy of the notebook report, showing the lab completion stamp, is to be turned in to the lab TA the following week.

The experiment “completion stamp,” provided by the laboratory TA, should be stamped in the lab notebook and should appear on the Xeroxed copy that is turned in. This date must correspond to the day the notebook report is due or earlier.
