• Lab kit [Also known as Lab-in-a-Box (Liab)] – Includes

• ANDY Board from Electronix Express • Parts kit and digital multimeter from Electronix Express • Velleman PCSGU250 or Digilent Analog Discovery 2 channel oscilloscope and

function generator – Link to the vendors is posted at www.opel.ece.vt.edu

• Lab Manual – Lab-in-a-Box: Introductory Experiments in Electric Circuits, revised 3rd Edition

by R.W. Hendricks and K. Meehan, available as an eBook.

• Pspice – Virtual Machine installation of Version 9.1 (instructions are on

computing.ece.vt.edu/wiki/PSpice_FAQ ) – This is our preferred version – Version 9.1 (www.ece.vt.edu/ece3274) – Version 10 from CD included in J.G. Tront’s book – Version 16.2 or 16.3 (computing.ece.vt.edu/wiki/Main_Page)

– If you use either Version 9.1, install both Capture and Schematics – Schematics tends to be easier to use and runs better on Windows 7 machines.

• MatLab – Available in Freshman Engineering software bundle: install the 32-bit version

• Instructions to activate license at http://swat.eng.vt.edu/Matlabtutorial.html • Contact SW.A.T. Team if you have problems (http://swat.eng.vt.edu/)

Parts pick-up • Tentatively scheduled for next week The days and times will be announced via email.

You need to purchase the equipment that is listed on www. opel.ece.vt.edu ◦ ANDY board, cables, either the Velleman or Digilent

oscilloscope, and a digital multimeter See the links posted at the OpEL Lab website

The room where GTAs are available to answer question and where you validate your circuits is the OpEL (Open Electronics Lab) ◦ located in Room 219 and 222 of Whittemore Hall. Hours of operation are posted at http://www.opel.ece.vt.edu/OpEL-

schedule.html

• ECE IT staff will assist with issues with the installation of PSpice and the oscilloscope software packages.

• http://computing.ece.vt.edu/wiki/PSpice_FAQ

• SWAT deals with any issues with MatLAB.

• Primary assignment of GTAs in the OpEL is to assist with technical issues about the construction and measurement of the circuits and grade the circuit validations. – They may be able to answer PSpice and MatLAB questions.

• Contact Dr. Dennis Sweeney with questions about ECE 3074 course policies, PSpice, and MatLAB, and issues about grading. – It is helpful if you attach the appropriate PSpice or MatLAB file to your

e-mail.

– College of Engineering has hired a MatLAB GTA. His contact information will be posted shortly on the course Scholar site.

• Contact Mr. David Fritz with concerns about the operation of the OpEL.

• Branden McKagen – 346 Whittemore Hall, mckagen05@vt.edu

– Please e-mail to request an appointment

• Bill Schumate – 350 Whittemore Hall, archer@vt.edu

• Available

– M-F 8am – noon and 1pm – 3pm

12

• Each student must come to the Open Electronics Laboratory (OpEL), Room 219 or 222 Whittemore Hall during TA office hours and validate their experiment before the deadline – 8pm on Mondays. • During the validation, the TA will ask the student to

perform a validation procedure.

• No late validations will be accepted without excused absence from the Dean of Students Office. – If you are waiting for a validation to be done after 8pm

and you signed up before 8pm, it is late! We strongly encourage you to get the validations done early.

– A zero will be given for the particular experiment (pre-lab, validation, and post-validation report) if the validation is not completed by the deadline.

• Students may do one (and only one) make-up lab, selected from one of the labs posted on Scholar or propose an experiment of their own design if approved by Dr. Sweeney at least one week before the make-up lab is due. – Due date for a make-up lab for experiments due in

Weeks 1-3 is 10/1/2012 for circuit validation and prelab report and 10/6/2012 for the post-lab report.

– Due date for the make-up lab for experiments due in Weeks 5-11 is 12/10/2012 for the circuit validation and prelab report and 12/12/2012 for the post-lab report.

Lab Grade

Pre-lab report 20%

Validation 30%

Report 50%

Total 100%

Extra Credit Surveys 5%

Each pre-lab and validations for Weeks 1-3 and 5-11 are worth 2% and 3%, respectively, towards the final grade. The post-validation reports from Weeks 2-3 and 5-11 are work 4.54% towards the final grade. Make-up labs replace the grade of one entire experiment (pre-lab, validation, post-validation report). Make-up credit is not given for the Week 0 post-validation report.

• All submitted work (both written work submitted via Scolar and experiments built on the ANDY board and presented for validation) is presumed to be the original work of the student and the Virginia Tech Honor code applies.

• The validating GTA and the grading GTA will forward information about validation and/or the pre-lab and post-validation reports to Dr. Sweeney, if there is any suspicion of copied reports and/or “dry-lab” experiments. • Evidence of cheating, either by submission of a copied

PSpice simulations, lab reports, recycled circuits for validation, etc. will be submitted to the Honor Court for appropriate action.
