My old PM3384A that I got used 15 years ago, has started a new behavior that is very annoying. After a 15 minute warm up, the scope does a power on reset, and then about every 2 -3 minutes after that, it does it again, and again, and again...
I'm looking for advice here. Is it worth troubleshooting this, or am I going to have to chase the rabbit down the hole only to find that it is not fixable? Or; is this a known problem with a known fix?
