scope probes

[ghostman11]

sorry if i am about to sound stupid but..............

am i right in thinking that you can fit any probe to a scope as long as it is the same bandwidth??

the reason i ask is because in order to learn as much as i can i was fortunate enough to come accross a scope that i could afford, however i need some probes for it and i cant seem to find any specificaly for that scope,
the scope in question is a wayne kerr 100 Mhz Dual Channel DTV 100. aslo i would very much appreciate any thoughts on what you think of this model or brand of scope.
sorry in advance to be a pain

It doesn't even have to be the same bandwidth. Just keep in mind what the bandwidth bottleneck actually is.

lol i cant belive i have spent so much time trying to track down the right probes when there was no need any thoughts or recomendations on what probes to get??.

Get something like this. I have two of them, and they actually have a bandwidth more like 200 MHz, rather than just 100 MHz.

thank you i will give them a try , anyone have any thoughts on the make and model of scope and if it would make a good general purpose scope

As long as the input capacitance and input impedance are compatible with the probe. ie: A x10 probe designed for a scope with 1MΩ input impedance would turn into a x100 probe on a scope with 100KΩ input impedance assuming the frequency compensation adjustment was compatible.

Those Tek probes on Ebay The Electrician suggested are nice since they have a switch to go between 1:1 and 10:1 modes. That way you can use a 10:1 mode when you need a high input impedance or a 1:1 mode when you want maximum sensitivity.
