Our Mirny v1.0 (ADF5356) board has 2 out of 4 channels that are starting to fail to output after months of operation. Both work after a hard reset and initial submission but one fails after a subsequent submission (showing a red light on the channel and no longer producing an output) and another randomly after many operation (usually once a day). This started with just one channel which slowly got worse until it was unusable and the second has started more recently. The error is silent on the atriq interface, I suspect a hardware issue. Has anyone experienced a similar issue?
