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?

Where was this Mirny card purchased from?

JBass You should contact your supplier in order to debug the issue with them and fix it in upcoming hardware revisions. AFAICT they don't monitor this forum or help out here.
