Hi James, Thanks for your answer.
I do not use a CASPER. I am using a ZCU102 platform. For the frequency, you're right. The initial period was 10ns, but I didn't get the expected response. So I started changing the frequency. Please do not hesitate if you have any other suggestions. Best regards, idir.
