I am using AD9656EBZ+HSC-ADC-EVALEZ with the 4 inputs ADC. Attached files shows that the 4 channels are synchronous until acquisition of 65536 samples. Beyond, at 131072 samples (look attached files), the four signals become asynchronous despite that the configuration has not changed, just the number of samples that has changed. I try to increase the acquisition time but the problem is still here. I am using VisualAnalog 188.8.131.52.
