My apology. I misunderstood what you were suggesting--I thought you wanted me to verify with REW that the delays were indeed bad. Now that I understand you are recommending sharing the result with Dirac Support, I agree. I have verified that the "bad" calibration was saved, and that re-calculating the delays produce the same flawed results, so I will take REW measurements and share the measurements and the project with Dirac Support. Perhaps they will find a root cause.Well, a verification with REW is probably more useful and in the end less time consuming. If it turns out the problem is real then you have it documented and you could forward that data together with your project to Dirac so they might be able to find out what went wrong.
Just checking, is this the correct link to report issues to Dirac: Dirac Live Support - Dirac Live Support - Confluence?
