I am experiencing an issue with very apparent stripes on camera readout.
Over time, a very pronounced stripe/band pattern started appearing and has a significant impact on image quality. The camera is electrically insulated so this is unlikely to be caused by ground loops.
This is not an issue with a specific piece but seems to happen to some extent with every one we have. First images appear normal with just characteristic CMOS line noise, but the longer the camera stays electrically connected, the more stripes appear. With higher analog gain selected, these stripes appear less significant. Temperature never exceeds prescribed operating range (usually at ca. 37°C). Have tried an external power supply.
I attach examples of dark images made with the cap on, showing how this pattern gets worse with time + their averaged line profiles. Has anyone dealt with a similar issue and have an idea what could be wrong? The vendor is not responding at the moment.
