New scope

Sylvia Else · 2021-08-21T04:06:35+00:00

My 40 year old scope seems to have failed again the same way it did a while back - one of the X-axis drive transistors has failed - the same one as last time. Could just be chance again, but one has to wonder.If I had a replacement, I'd use it, but either I only sourced one last time, or I've lost the other(s). Either way, I think I should cut my losses, and get a new scope.My needs are fairly basic - after all, I lived with a 20MHz scope for forty years. A USB/PC one would probably suffice.Anyone have experience with such a device?Sylvia.

It takes a scope to fix a scope.

Sometimes, perhaps. But in this case, the symptom is that half the x-axis doesn't get used, with a bright dot in the middle instead. And I already knew that failure of a transistor in the final x-axis amplifier could cause this.

I was right. It fixed itself.
