Dynamic Range Enhancement of High-Speed Data Acquisition Systems

摘要

The innovation is a technique to overcome hardware limitations of common high-speed data acquisition systems in order to be able to measure electronic signals with high dynamic range, wide bandwidth, and high frequency. Electronic waveforms exist that exceed the capabilities of state-of-the-art data acquisition hardware that is commonly available. That hardware is still not sufficient to capture these waveforms with enough accuracy and certainty for coherent results. The electronic waveforms that need to be measured simultaneously contain wide bandwidth, high frequency content, a DC reference, high dynamic range, and a high crest factor. To record these waveforms, the current data acquisition hardware needs to increase simultaneously its internal analog bandwidth, quantization bits, sample rate, and analog signal-to-noise ratio. Attempts at recording these waveforms were previously limited to inferior statistical techniques that were not able to provide instantaneous waveform recordings that were unique from the statistical, time-averaged collection.
