Calibration of data acquisition systems is important for testing infrared focal plane array(IRFPA) detectors. Based on the analyses of the working principle and characteristics, a calibration method for data acquisition systems is presented using general devices and testing systems of IRFPAs. The practical testing results indicate the effectiveness of the method, which could calibrate the key performance metrics of data acquisition systems, including acquisition error bounds, acquisition linearity, background noise, and acquisition frequency.
