The Integrator Operational Amplifiers Board for NI ELVIS II/II+ provides hands-on experiments in OpAmp circuit design and analysis. Teaching resource topics include various amplifier configurations, voltage to current conversion, and signal generation.
The OpAmp Applications Lab is based on the NI Educational Laboratory Virtual Instrumentation Suite (NI ELVIS II) platform and uses software developed in NI LabVIEW Graphical Programming Environment, using NI’s Virtual Instruments technology. All hands-on labs are conducted on the supplied preassembled printed circuit board. The students can study the output signals of the circuits depending on the input stimulus. Course manual is embedded in lab software for easy access to ad-hoc theoretical materials during the lab. Experimental results, including student name, date & time, etc. may be exported and saved in MS Excel format. Course software has simple and intuitive user interface. The student uses the prototyping board for the hands-on experiments with the electric circuits, as described in the operations manual. Circuit schematics and course instructions for each particular lab are presented on respective front panels and in the manual. Corresponding sections from the manual are available on respective Help screens, so that the students may refresh their memory on the appropriate topic without interrupting practical work on the lab. Step-by-step instructions, available for each lab, describe all consecutive operations that the student must perform, along with the results that must be obtained. The experimental results can be saved in MS EXCEL format for later review and grading.
