Hi everyone,
I've just added a DSA602 (with 32, 33 and 72 plugins) to my Tektronix collection - even though it's a different era the engineering that has gone into these machines seems a great tribute to some of the earlier models. The instrument itself is in fine cosmetic condition, however hangs on boot-up with the message "Comm test in progress". After looking at the service manual and some investigation, it seems that the problem is with the kernel of the executive processor, and that therefore the fault is likely with either the main CPU or associated memory cards. As this is still a bit vague I was just wondering if anyone has experience of solving this or similar problems before, or if there are any common causes of this fault?
Thanks for your help,
