Electric signal source device used for oscillatory scanning infrared earth sensor test calibration

The invention discloses an electric signal resource device to swing sweep infrared earth sensing test calibration which is made up of the CPU, analog output module, the signal resource generating module, the power supply and the LCD. The CPU is connected with the analog output module and the signal resource generating module by the STD bus; the LCD is connected with the CPU by the VGA interface. According to the need signal and the time sequence of test calibration, the CPU works out the signal resource generating data according to the distributed parameter which the data controls the signal resource generating module and the analog output module. At the same time, it outputs the signal need by the sensing device calibration to finish the test calibration.
