Plagiarism Policy: All reports for this laboratory are prepared individually. It is expected and encouraged that students help each other with the concepts and the data gathering/analyzing stages of the lab. However, the report is an individual effort. The standards of the university on plagiarism are published and will be enforced. See CSUS policy: http://www.csus.edu/umanual/student/UMA00150.htm On the first occurrence of potential plagiarism, the reports involved will receive minus the value of the lab report points. I have no way of knowing which report was the “master” and which was the “copy”. Both reports will receive the minus score. On a second occurrence, the reports will be submitted to Academic Affairs for disciplinary action. General Notes 1. There are many deadlines in the lab schedule. Pay attention to the schedule and meet the deadlines! 2. Please report any broken test equipment, scope probe or test lead immediately to the instructor. We have spares on hand and will fix the problem as quickly as possible. 3. Please report any difficulties you encounter with the lab computers or software. While it is usually “operator error”, you may have found a unique error that needs fixing. Required Supplies: Prototyping Breadboard Suggested models are: Global Specialties GS-830 or Twin Industries TW-E41-1020 (includes precut wire kit) Available from: www.amazon.com, www.digikey.com, www.mouser.com Composition Book Minimum Specifications: 9.75 x 7.5-inch, 100-page, graphed, side-bound Available from: Academic bookstore, or where office supplies are sold ECS Hive Moodle will be used to communicate announcements, laboratory handouts, etc., and is where students will submit laboratory reports, and scanned images of “engineer’s notebook” online. Students are encouraged to visit the class page often. You can login to the ECS Hive at: https://ecshive.ecs.csus.edu/portal using your regular ECS computer account user name and password. If you do not already have an ECS computer account you can get a free account at: http://www.ecs.csus.edu/index.php?content=accounts PSpice Students may wish to store and transport their own PSpice files via a USB flash drive. The lab computers have the PSpice program on their hard disks, but students should maintain all their circuits’ files on their own portable media or transfer files from the computer when done. Each tudent is responsible to make his/her own arrangements to access a computer in order to complete the required PSpice simulations outside of the scheduled lab time, if necessary. You can access PSpice via the ECS Hydra Terminal Server using your regular ECS computer account user name and password. Laboratory Objectives After this laboratory students will be able to: Use laboratory test equipment to measure characteristics of electronic circuits Use circuit simulation software to simulate characteristics of electronic circuits Build circuits using semiconductor devices including PN diodes, BJTs and FETs Build circuits using operational amplifiers Document results from laboratory experiments in a professional manner Laboratory Work Groups: Students will work in groups of two (if needed, one group of three may be allowed in a section with an odd number of students). Work Periods: Each experiment is scheduled for one, or two lab meetings. All lab work should be done during the student’s scheduled lab period. Attendance will be taken at each lab section meeting, and the instructor will keep a record of progress. Access to RVR-3017 is controlled and will be allowed only during your scheduled meeting times. Room 3017 – Notes on equipment and policies 1. No food or drink in the lab. The equipment is way too expensive to risk damage by lunch. 2. Please clean your station before departing the lab. Replace all cables, parts and portable equipment to the proper places. 3. The user guides and manuals for the test and measurement equipment in the lab are posted on the ECS Hive course site. 4. Test devices and parts will be supplied to the lab team. Please return useable parts to the proper bins and destroy damaged/unusable parts. Keep the lab areas clean and neat. Do not leave anything at the work stations when you leave. Discard all trash in the appropriate trash can or paper recycling bins. Food and drinks are not allowed in the lab!!! Procedures, Data Documentation, and Lab Reports When to Write: Students will record in their “Engineering Notebooks” the procedure and data corresponding to each experimental step as the experiment is being performed. This data will be reviewed, discussed, and checked-off during in lab experiment demonstrations and will be part of the student’s laboratory grade. After each experiment, a Lab Report of selected conclusion(s) will be requested by the instructor, and must be submitted via the ECS Hive website by the due date. (Note: Students will demonstrate and discuss the results of their experiments during their assigned laboratory period.) Lab Reports: Students will document their results in a professional manner using word-processing and graphical software to create reports. One week after the last lab period for each experiment, the student will submit a final lab report. Reports shall follow a Technical Writing style/format. Acceptable reports will include a title page, followed by an abstract page, and then pages containing a technical discussion (“Engineering Story”) which addresses and answers the selected procedure(s)/conclusion(s). There are no separate procedures, data, and conclusion sections in the final lab report; however, relevant data must be cited and discussed where necessary to support all conclusions. All reports must be clear and easy to read (give the reader an “Engineering Story”), including the ability to zoom-in to see details on any plots or graphical data submitted. Numerical data should be summarized in tables. The handout will describe the procedure for a given step, but the student must record the procedure in his/her own words (DO NOT copy the handout). A good indicator for the amount of written detail required is that another engineer should be able to follow your reasoning and conclusions, as well as be able to reproduce the experiment from the laboratory notes and get the same results. Graphical data may be shown as Excel objects, or objects from a similar spreadsheet/graphing program. Waveforms may be described in words (e.g. 2Vpp sine wave at 600 Hz with 0.5V DC offset) or captured from the scope. All equations in the lab report must be neatly typed (preferred) using an equation editor such as MathType, the Microsoft Equation Editor or other appropriate software. Or the equations can be neatly hand written in pen. Non-mathematically formatted equations submitted on lab reports will R2 receive a point deduction. For example: v0 (t ) vi (t ) and not v0(t)=vi(t)R2/(R1+R2). R1 R2 The Title Page: The first page of each final report shall be a title page. In the upper right-hand corner of the page on five lines, write: Author’s Name - the name of the author of the report (underlined) Partner: Name -the word “Partner:” and the name of your lab partner EEE 108L Section x -the course name and laboratory section number xx/xx/xxxx Report Date - the submission date of the lab Centered on the page, write: -The experiment’s TITLE, and beneath it -The NAME of the author of the report The Abstract Page: The second page will contain the abstract for the experiment. Do not put the abstract on the Title Page. The abstract should be written after the procedures/conclusions section of the report is finished and then placed at the beginning. This way, the student can reflect on the entire experiment before writing the abstract. The purpose of the abstract is to briefly provide a technical discussion and acquaint the reader with the content of the report that follows (again, following a Technical Writing style/format). Abstracts for experiment reports should summarize the major accomplishments of the lab rather than detail every step. In general, do not put numerical results or raw data in the abstract. Sometimes, if the purpose of the experiment is to establish performance relative to a well-known benchmark, one might put that number in the abstract (e.g. at room temperature). (See also the American National Standards Institute- ANSI Z39.14.1979) Note: Remember, an abstract is not an introduction or a conclusion to your paper, nor is it an area to pose questions to the instructor or let him know what you learned. An abstract is a technical summary that allows a reader to get a technical top level understanding of what is being addressed, what was accomplished, and what was concluded with respect to a particular technical topic. The Procedures/Conclusions Section: This section will most likely be done after the laboratory period. The handout will contain numbered items that the student will be asked to address. The student should write his/her responses in order and with enough supporting data to validate all conclusions (remember you need to provide the reader with an “Engineering Story”). Be sure to write your answers as complete thoughts and to follow a Technical Writing style/format. You will lose points if your responses do not make sense when read in isolation. For each response, you should cite relevant data from your engineering (lab) notebook to support your conclusions. Graphs may be required as a discussion point in your lab report. Unless instructed otherwise by your lab instructor, generate via software (e.g. MS Excel, PSpice plots) all graphs, and insert into the discussion section of your report. Ensure that all your graphs are labeled and titled (i.e. “Figure #- Title”) accordingly, in the lower left hand side of the graph, while ensuring that the graph is centered on the page. Please be sure to distinguish between simulated and measured data. If you are to make a graph from your measured data, do not submit a graph taken from PSpice. One way to avoid misrepresenting data is to include either the word “simulated” or “measured” in the title of every graph. Tables may also be required as a discussion point in your lab report. Again, generate via software all tables. Ensure that all your tables are labeled and titled (i.e. “Table #- Title”) accordingly, centered above the table, while ensuring that the table is centered on the page. Use color pencils, ink, or software generated call-outs to highlight (bring attention to the reader) items on a graph or table; however, make sure any and all markings are annotated appropriately. In addition, all report formulas/equations must be generated with math type fonts. Ensure that all equations are uniquely labeled (i.e. “Eqn- #”) accordingly, and when necessary are called out by their equation number throughout the discussion. Lab Report Submission: Each student must write a final lab report for each experiment. Students may confer with other students about items in the final report. However, students may not copy or modify another student’s answer, even their own partner’s answer. Do not use graded lab experiments from the last term as a guide to writing reports. The experiments change slightly each semester, and copying is easy to detect and prove. Copying answers from an old report is considered cheating and appropriate penalties will be imposed. All reports must be submitted in PDF format on the laboratory ECS Hive page. Reports submitted in other formats or through other methods such as email or on paper will not be accepted. The final lab report shall be generated on a standard 8.5” x 11” paper size format. Each page (except the title page) must have the page number out of the total page count in the right footer section of the page (i.e. Page 1 of ##). The reports must be computer generated (use double spacing to make room for comments). Course Policies 1. You are expected to arrive on time and remain until all requirements for the laboratory assignment have been completed. Laboratory demonstrations must be performed during the assigned laboratory period. Make-up labs will only be allowed under extraordinary circumstances, at the discretion of the instructor. 2. You are responsible for all material covered and announcements made during the laboratory whether or not you are present at the time. Attendance is therefore strongly encouraged. Students are also encouraged to visit the ECS Hive page often, as materials and announcements are typically posted there. 3. No late work will be accepted. Assignments are due on the day and time stated. Those turned in late will only be accepted under extraordinary circumstances, at the discretion of the instructor. If a late submission is accepted, penalty points will be deducted based on the amount that the assignment is late. 4. All grades are final two weeks after an assignment is returned to the class. Any suspected errors in grading should be brought to the attention of the instructor immediately. Judgments regarding the number of points to deduct for a particular error made in an assignment are not subject to review. 5. All students are expected to obey the University Academic Honesty Policy at all times. Students should review this policy, which is available online at http://www.csus.edu/umanual/AcademicHonestyPolicyandProcedures.htm . While students are encouraged to discuss course material with their peers, all assignments turned in for credit should only be discussed in a general way. Any violations such as copying the work of other students will be dealt with severely, up to and including assigning a grade of F for the course. 6. Office hours are provided to allow students to ask questions outside lab. Any additional meetings with the instructor are by appointment only. However, students are highly encouraged to ask questions in lab so that everyone can benefit. Remember, the only dumb question is the one that doesn’t get asked! 7. Email should be used for urgent matters only, such as notifying the instructor if you must miss a lab. Email should not be used to ask questions on material more appropriately asked in lab or during office hours. All emails should include a valid subject line briefly describing the topic of the email, not just “Hi” or other generic titles. All emails must also include your name, and the name of the class you are inquiring about. Do not include your student ID number in emails, as that is confidential information which should be carefully protected. 8. It is expected that students will show consideration for others by putting cell phones and pagers into vibrate or other silent modes during lab, and by leaving the room to take any urgent calls. Repeated violations of this policy will result in the offending party being prohibited from bringing their cell phone or pager to lab. 9. Special accommodations will be made for students with conditions requiring them, providing that official documentation of the condition is provided to the instructor no later than the second week of class. If you have a disability and require accommodations, you need to provide disability documentation to Services for Students with Disabilities (SSWD).
