Hi all,
I bought this probe off e-bay:
I thought it would be just the job for my 350Mhz analogue tek scope, but in small print on the probe it says it's for use with Tek TDS400 series scopes only. Why the limitation? The other thing I've noticed is that I can't seem to compensate this probe as there doesn't seem to be a conventional adjustment screw beneath the (tiny) access hole visible in the photo. The 1k square wave resembles dragon's teeth so it really does need the scope capacitance tweaked a fair bit before it's usable. Does this probe require some special service tool to tweak for compensation? Finally, there's a spring-loaded pin that's pressed home when the BNC connector is plugged into the scope. What's that do? THanks. More in the "dumb questions" series later. p.
