So I am getting an oscilloscope Thursday in the mail, from a generous donor. He had a list of scopes he had, and told me it was "a really nice 4 channel". That would either be the 7834, or the 7854, both 400mhz scopes. I doubt probes are included in this deal though. My question is, is there anything special about an oscilloscope probe that separates it from say, a multimeter probe? Also, as you get higher in the frequency range, do I need special probes?
