Re: [casper] Help with setting up KatADC on ROACH2

[Dale Gary]

Thanks Jack and Jonathan for the replies. We have the clock signal coming into the KatADC on zdok1 (the second one). I wonder if there are jumpers on the board that set the clock source and may be misconfigured? I have a dim recollection of that sort of issue.  Regards, Dale Sent from my iPhone On Sep 22, 2026, at 3:32 AM, Jack Hickish <jackhick...@gmail.com> wrote:  Hi Dale, As far as I'm aware there are no special settings needed for QDR - everything is baked into the firmware. Does the failure give any useful information? Has the new board passed its factory QDR tests at digicom?

However, the new ROACH2 board fails its QDR test on all three QDRs.  Are there some settings we have forgotten?  Any other ideas?
