Abstract:
1. A system for acquiring data of a multi-channel signal, comprising: a channel-voltage transmission module disposed in a shield room blocking electromagnetic waves, connected with a plurality of channels from which analog signals are output, and configured to generate a serial digital signal having information about the analog signals and information about the channels from which the analog signals are output; and an optical fiber cable through which the serial digital signal is transmitted from the channel-voltage transmission module to the outside of the shield room; wherein the channel-voltage transmission module includes: an analog switch configured to select an analog signal output of a selected channel from the analog signals output from the plurality of channels; an analog-to-digital converter (ADC) configured to convert the selected analog signal into a serial digital signal; a clock/counter configured to generate a channel selection digital signal for the analog switch to select a channel; and a parallel-to-serial converter configured to convert the channel selection digital signal into a serial channel selection digital signal and combine the serial channel selection digital signal with the serial digital signal to generate a serial digital signal having information about the analog signal and information about the channel from which the analog signal is output.
