【Abstract】 Following an analysis made on the cause of "data mismatch"is the time-sharing sampling process of multichannel data and its affection on the metering results,the author introduces a newly developed type JDC multi-channel data sampling card and its construction principle.The card consists of several AD converters,latches,filters and address decoders,and has the functions such as 16 bit binary resolution,multi-channel simultaneous data sampling,sampling rate at 100kHz per channel etc,and data mismatch is overcome.the card can be inserted into the slot of IBM or compatible machines and is suitable for one physical event occurrence with simultaneous multiple parameter outputs for high-accuracy data sampling applications.更多还原
