DATA ACQUISITION SYSTEM OF A MULTICHANNEL SIGNAL WHICH DOES NOT REDUCE A SAMPLING TIME EVEN CHANNELS MEASURING A SIGNAL IS INCREASED

摘要

PURPOSE: A data acquisition system of a multichannel signal is provided to enable a computer to conveniently obtain the multichannel signal transmitted from the outside.;CONSTITUTION: A channel-voltage transmission module(110) is located inside the shield room which secludes electromagnetic wave or electromagnetic wave. The channel-voltage transmission module is connected with a plurality of channels which an analog signal is outputted. The channel-voltage transmission module generates a serial digital signal from an analog signal outputted from a plurality of channels. The serial digital signal has information about the analog signal and has information about channel which the analog signal is outputted. An optical fiber cable(120) transmits the serial digital signal from the channel-voltage transmission module to external side of the shielding room.;COPYRIGHT KIPO 2011
