Abstract
A multi-channel timing calibration device and a method applicable thereto are provided. The device includes: a plurality of channel inputs, at least one relay switch, at least one comparator, at least one first multiplexer, and a time measurement chip. The at least one comparator is connected to the at least one relay switch, and connected to a reference voltage or a digital analog converter. The at least one first multiplexer has different signals for different channel groups and outputs a signal of a designated channel. The time measurement chip calculates a timing difference of each of the channels of each of the channel inputs as a basis for delay of the timing signals.
