Hi everyone, We have trouble here in the laboratory trying to calibrate the ADC's for our ROACH2. It is still the same problem we had been having a month ago.
We started working with the paper: 'CHARACTERIZING THE PERFORMANCE OF A HIGH-SPEED ADC FOR THE SMA DIGITAL BACKEND' and the code provided. Modifying the code as necessary we have been succesfully able to calibrate the ADC connected to ZDOK1. The other ADC however does not seem to get calibrated at all. We checked if it was a hardware issue by switching the ADC's from ZDOK port and the problem switched too. Somehow the ADC board in ZDOK0 is not calibrated correctly. Since it works on one perfectly and not on the other the obvious place to look was in our code but so far we have not been able to find a mistake in the code. At the moment we are a bit stuck as to ideas what could be causing this problem. Any suggestions from the community? Regards, Tom
