1. Grade breakdown. Your lab grade will be determined from the following breakdown:
Reports 75%
Performance 25%
The lab instructor will award your performance grade based on his/her observations of your behavior during the lab period. If you are contributing to your group, then you will receive
a full 25%. If you are just standing around doing nothing, you will receive 0%.
2. Make-ups. ALL labs must be completed for you to receive a lab grade. If you do not
complete an experiment, you will receive a "0" for your lab grade. You must be present during lab to get credit. Make-up labs must be arranged either prior to the absence, or afterward with a doctor's excuse. Attendance will be taken during all labs.
3. Preparation. You are expected to be prepared before coming to lab. Read the lab before
coming to class, complete the preliminary exercises, if any, and review any topics you are unsure of. There will NOT be a lecture during the lab period. The instructor will NOT answer questions during the lab period over topics you should know from the lab manual.
The instructor's presence during the lab period is to oversee the lab and help you with any mechanical trouble you are having with the equipment. If you do not understand material from the manual, see the instructor before the lab period.
4. Data. All data must be taken in PEN. It must be signed and dated by the instructor before
you leave the lab.
5. Lab reports. Lab reports are to be handed in at the beginning of the lab period immediately
following the period during which the lab was completed. You will be graded on spelling, grammar, organization and writing style, as well as on content. Each group will turn in one report.All lab reports must be written using Microsoft Word. The lab reports need not be lengthy, but should follow the following outline.
1. Title page. Title of lab, names of students, name of instructor, section number, date
of lab, date of report (due date).
2. Goals. One paragraph outlining the goals of the lab.
3. Accomplishments. A summary of your accomplishments -- what you have learned
during the lab. Discuss discoveries, difficulties, verifications of theory, etc. Relate
these to the goals of the lab.
4. Discussion. A discussion of your results, which follow in the next section. You
must refer to labeled tables and plots. Include answers to questions posed in the lab
manual and discuss error, if appropriate. Include all calculations.
5. Results. Include your measured and calculated data. Your data must be in either a
properly labeled table or graph, or both. When you refer to these, it must be by table
or graph number. Every table and graph must be referred to at least once in the
report. See the attached pages for examples of a table and graph. For small amounts
of data, use a table. For large amounts of data, or when visualization is important,
use a graph. Be sure to include units!
6. Raw data. Include at the end of your report the raw data you took in lab, including
your instructor's signature. Label this data as APPENDIX 1: RAW DATA.
Parts 2 and 3 above are to get you to think about how the lab experience relates to the class material and how the information gained during the lab has helped your understanding of the class topics.
6. Discussion of error. When you discuss error you may, if you wish, blame the equipment. If
you do, you must discuss both the source AND RANGE of the error. For example, if you can read a dial to within 5%, this range of error cannot completely explain a difference of 25% between theory and experiment, unless it is compounded. Remember, the most common cause of error is unfamiliarity with equipment.
7. Be nice. Please treat the equipment kindly. Be nice to sensitive things like connectors,
switches and dials. To be safe, there will be no food or drink allowed in the lab.EXAMPLE OF PROPERLY LABELED PLOT

Spring 2006
This document addresses safety considerations for students participating in the ECE 407 laboratory. Students should review all safety material provided by previous lab supervisors and be aware of the health effects of electrical shock. This document describes specific potential hazards for ECE 407.
Electrical Shock
Any time students use electrical equipment there is a possibility of electrical shock. In the ECE 407 lab there is little potential for shock since most equipment produces low-voltage, high-frequency signals. By using caution and common sense, a high level of electrical safety can be maintained. Whenever using electrical equipment of any kind, students should be on watch for frayed and broken plugs, wires, and connections. Any potential hazards should be immediately reported to the lab instructor.
Microwave Exposure
Several ECE 407 experiments involve using signals at microwave frequencies. Power levels employed are well below those which give rise to electromagnetic heating. However, the subtle physiological effects of microwave energy are still uncertain, and students should take care to minimize their exposure to microwave energy. The following guidelines should be sufficient to provide a safe environment.
1. Never look directly into the open end of a waveguide or transmission line.
2. Never radiate EM fields in the direction of yourself or other people.
3. Never perform measurements while anyone is inside the anechoic chamber.
Note that the measurement software has been written so that RF output is turned off at all times when measurements are not being performed. However, students must be aware of the presence of persons inside the anechoic chamber, and make sure that the measurement process is not initiated when the chamber is occupied.
If students have ANY questions regarding safety, they should immediately discuss them with their lab instructor.下载本文
