Abstract
An individually laboratory-based Centralized Signal Distribution System has been developed to provide known signals in labs for undergraduate core electrical engineering and technology courses. The system consists of a general purpose PC running LABVIEW software which controls three Arbitrary Waveform Generators. LABVIEW, a graphical programming language, allows easy programming of the instruments. The source code for LABVIEW looks like a flowchart, while the user interface appears on the monitor as the front panel of a virtual instrument. The presently developed system is programmed to provide basic signals for introduction to signal waveform analysis and oscilloscope operation, phase-locked waveforms of integrally related frequencies for digital applications, AM and FM signals for elementary communications experiments, and frequency sweeps for testing of analog transfer functions. Signal parameters such as DC offset, frequency, phase, amplitude, waveform, and modulation may be readily changed by the lab instructor.
