NI ELVIS What is it?

• System appropriate to teach electrical system
  design and prototyping
• System designed to develop LabVIEW-based
  measurement applications aided by a suite of
  virtual instruments
• Suitable for measurements and design applications
  in EE, ME, Biomedical and physical sciences
  instructional labs
• Source code for virtual instruments provided
• Basic design developed by an instructor
• Curriculum under development

3
Overview

• Integrated
• All the functionality needed to develop
  measurement applications in one single system
• Industry standard user interface
• Open, flexible
• Modifiable software rather than stand-alone
  executables
• Slot for a protoboard or custom signal
  conditioning PCB
• Adaptable to various experiments and courses
• Robust
• High-voltage and short-circuit protection

4
Overview

• Easy to use / repair
• Standard connectivity with banana and 9-pin D Sub
  (Digital I/O)
• Smooth transition from manual knob to LabVIEW
  front panel
• Removable protoboard, protection board
• Low cost
• Fraction of the cost of a suite of traditional
  instruments
• Curriculum
• Proposal submitted to NSF for the development of
  six courses
• Contact National Instruments if you are
  interested
