Assumptions and Limitations Assumptions ELVIS bundle from NI in working condition ELVIS bundle from NI in working condition The group can create virtual instruments that are not provided The group can create virtual instruments that are not provided Limitations No current or inductance measurement capacity No current or inductance measurement capacity Measurement inaccuracy Measurement inaccuracy Limited knowledge of internal design Limited knowledge of internal design

End-Product Description and Deliverables Selected labs will be converted to ELVIS system New instructions for selected labs Documentation of conversion process

Present Accomplishments Familiarity with ELVIS hardware and software Carried out EE 201 labs 1, 5 and 6 with the ELVIS system Produced new documentation for completing EE 201 labs 1, 5 and 6 with the ELVIS system

Approaches Considered and Used Considered Creating new virtual instruments Creating new virtual instruments Individually converting every lab for use with ELVIS Individually converting every lab for use with ELVIS Used Decided to use Virtual Instruments provided by NI for their ease of use and functionality Decided to use Virtual Instruments provided by NI for their ease of use and functionality Focused on key labs which made use of different features of ELVIS Focused on key labs which made use of different features of ELVIS

Research and Design Activities Research Read National Instrument’s ELVIS manual Read National Instrument’s ELVIS manual Researched how others are using ELVIS Researched how others are using ELVIS Design Updated labs to make use of unique capabilities present in the ELVIS system Updated labs to make use of unique capabilities present in the ELVIS system

Implementation Activities Took notes as we implemented several EE 201 labs using ELVIS Created new lab instructions for the labs that could be completed with ELVIS

Testing Activities Asked a EE major to follow our new lab instructions Asked a ChemE major to follow our new lab instructions Reviewed our own instructions to ensure completeness Tested the accuracy of ELVIS
