Help Identifying Probe Found with Type 500/53 Cart
|
I found this probe in the drawer of a Tek Type 500/53 scope cart. It doesn't have a part number or brand on it. Any ideas? Photos here: https://groups.io/g/TekScopes/album?id=271763

That’s a P510, an early Tek probe that was sold with the Type 531 and 535 mainframes in 1953. The cable is ordinary coax. At the introduction of Types 541 and 545, this probe was replaced by the P410, which has special resistor-coax cable that can make it to 30MHz without ringing.

Thanks for the quick feedback. P510 it is. Not sure what i'll do with it, but that applies to most of the test gear I have. I'll add it to my growing 'collection' of Tek stuff.

Use it with any scope 15MHz or less.

I see where the P510 is used on the Tek 315D scope. A question: If one owns a 315D scope but is using a different Tektronix probe, is there anything to be gained by using the correct P510 probe, other than perhaps increasing the collector value of the 315D?

Not that I can think of. Until you get above about 100MHz, most scopes’ probe input is a completely generic 1 megohm with some C in parallel. Any voltage probe will match that as long as it can compensate for C.
