| Abstract: | During the process of data collection, there exist inaccuracies and some defects, such as poor interference immunity, a new ADC dynamic testing method is proposed based on the high-speed ADC dynamic test platform; including the testing methods and basic principles ; verification indicates the noise signal impacts greatly on ADC properties. However noise signal can be applied to effectively improve the performance of the ADC. Testing and analysis has been carried out with ADI"sSAD6645-105,Sand the results show that theStesting method has such advantages as higher safety, higher reliability, and higher accuracy, and can improve the ADC conversion performance,S theSconvertingSprecision,Sand the anti-interference ofSADC. |
