摘要：
An easy-to-use and low-cost quasi-synchronous multichannel digital sampler controller to aid routine laboratory ac measurements by digital sampling is described. Using a single digital sampling voltmeter, accurate measurements of ac quantities can easily be done with uncertainties of a few microvolts per volt. Measurement results and consistent uncertainty calculations are described.
