We are using AD9680 to capture data from R&S SMU200A to verify something.
We found the data that capture from these 2 channels are not synchronous.
The data seems to have time difference between channel A and channel B.
Our environment is:
SMU200A channel A connect to AD9680 channel A directly.
SMU200A channel B connect to AD9680 channel B directly.
Then, send the same waveform at the same time.
We got the data by the VisualAnalog and it output the capture data to 2 files (one is for ch A, and another is for chB).
Before we save the files, we also check them by the waveform analysis in VisualAnalog and the graph seems OK.
But, we analysis the data and found they have about 11.05us delay like below picture.
Have any suggestion or way to synchronize AD9680's channel A and channel B ??
Or my operation has something wrong ??
