Hello everyone! Thanks for all the great responses. I looks like it will boil down to creating something own.
@Florian: Excellent idea with the DIL socket! I already thought about putting together something own, but those sockets for the tip connection didn't come to my mind. Other probes suitable for this application aren't available, so I'm stuck with this 3.5mm stuff, I guess. Also the SMB/SMC connector with the spring-loaded 3.6mm diameter is a good idea! @andy, Peter: Building the probe using a series resistor and an SMA/MCX connector on my own also came to my mind, but just a little too late, since the PCBs are being manufactured already. But it will definitely be an option for next time. Since you are suggesting it, I believe it will actually work ;) @Bertho: A little PCB for the ground connection seems to be a good idea, thanks for that! @Roger: The resistive part of the load isn't that much of a problem, since it does not interfere with the controller operation. I'll have to take it into account, but that's much less of an issue than a capacitance of a few pF. The signals are also quite low-impedance (at least when it comes to DC), so that's ok.
