Hi, have just purchased a Tektronix 2215A from ebay ...and need to buy 2 probes to make sure its functioning properly when it arrives....& I'l be using the scope for learning and tinkering with small micro-controller projects and other pcb stuff..so any advice or conformations would be appreciated as I have to buy something today/tomorrow

I have made a small table with scope specs ...and 4 different probes ..would I be right in thinking the Top Quality 100MHz Oscilloscope Scope Probe is better than the rest..in every area?

here are my assumptions of preferable probe characteristics:

bandwidth :: higher than scope
input resistance :: lower than scope
input capacitance :: lower than scope
compensation range :: must include the scope's cap value ..& wider range is better than narrow
rise time :: lower than or equal to scope
working voltage :: higher than scope...or at least higher than voltage levels I expect to be working with

that's very helpful Bob ..thanks, I'm halfway through reading it; very well explained

one thing I don't understand, at your link there is a little web program( LINK ) you can enter your scope model and probing requirements

I choose:
2200
voltage
passive
5 to 50mhz
0-500v(..as it doesn't allow 0-30v)

and it comes back with 2 probes ...the p6101B has an iC of 100pF ..while the scope has an iC of 20pF ..which doesn't really make sense from what I'v read ...why would you want the probe iC 5 times higher than the scope

Good question. I would suggest e-mailing them and asking. I have had excellent responses from them in the past. Quick response time too.

Cheers for now, Bob
