Hi Axel,
Thanks again for your helpful suggestions. We were finally able to resolve the issue. It turns out that every time a measurement point was taken, a new buffer was created in the SMU’s memory. Given the high data traffic between the computer and the SMU, the memory eventually became full—or, more accurately, new memory could no longer be allocated, which led to the SMU crash.
I made some updates to the SMU driver in the “measure” function by adding a buffer-clear operation before each new measurement point. This ensures that memory is properly managed, and everything is now running smoothly without any crashes. I din’t had the time to check other SMU drivers, but this problem could be a general problem.
Thanks again for your assistance!
Best regards
