Improve the Distortion of a Signal Generator to Measure a Wide-Dynamic-Range Data Acquisition System (DAS)

Abstract: Developing a wide-dynamic-range DAS presents design and test challenges. The main test challenge is the lack of signal source with a better THD and SNR. Both the THD and SNR of a signal generator become critical concerns when the DAS is rated for 100dB SNR and -120dB THD. This article address a way to improve signal generator distortion performance to evaluate ultra-low distortion DAS.
