METHOD FOR CALIBRATION OF GAIN AND OFFSET OF ANALOG/DIGITAL CONVERTER

摘要

PURPOSE: A method for calibrating the gain and offset of an analog/digital converter is provided to correct input and output data by correcting the gain and offset of the analog/digital converter. CONSTITUTION: A plurality of preset signals are transmitted from a signal source(10) to a data collecting device(20) and a data operating device(30). The data collecting device transmits the processed signal to the data operating device by processing the preset signal. The preset signal transmitted from the signal source is stored in the data operating device. The gain and offset of the analog/digital converter is operated by comparing the preset signal with the transmitted signal. The gain and offset is transmitted to the data collecting device. The gain and offset of the analog/digital converter is changed into the gain and offset operated by the data operating device.
