Visualization, Research And Development Of Multi-channel Pulse Signal Generator

With rapid growth of the modern scientific technology and extensive use of the electronic, compute and Internet technologies, strong vigor are injected into the instrument technology. At same time higher requirements which are brought forward with the development of the high-tech expose the limitation of traditional instrument. Virtual instrument, the deep-level combination of traditional instrument and computing technology, is a remarkable achievement in these fields. It breaks the traditional mode which the parameters are always defined by the manufacturers and enable users exert their talent and imagination sufficiently as well.Our research is mainly about visual multi-channel pulse signal generator (virtual instrument). The system is compose of PC (desktop or laptop), software kit, SCM (Single Chip Micyoco), double-channel SRAM, large-scale programmable system-level EPM7000 series chip. With 'the signal waveform editor' software develop kit , the multi-channel pulse signal with more complexity, higher accuracy and strict synchronous relation, which use for testing electronic and other devices, can be generated and output quickly and visually through various edit methods.Besides, we can improve system performance by increasing clock frequency and selecting high efficient component, and realize high frequency signal generator and various waveform signal generator. This research successfully transform instrument from simulated style to digital ones, make it possible for the home made instruments to achieve high performance and envision a bright future for the electronic instrument development.
