Good morning, everyone, I am currently designing a real-time measurement software based on the crio 9039. There is an FPGA part where I am acquiring the signal one sample at a time that I read from the rt processor using a reference to the FPGA and the Read/Write function to a command. However, when I acquire a sinusoid I find that there are samples that are not perfectly aligned with the others. I thought it was a chassis grounding problem but it's not that.
Can someone help me?
