I was recently given a Tektronix 2210 oscilloscope (from 1989) but I need to buy some probes for it. Next to the connector on the scope it says 1M Ohm and 25pF. I know that I want to match the resistance and capacitance of the probe to my scope.
I can find a 1M Ohm probe pretty easily but cannot find a probe with a 25pF capacitance. How close of a matching capacitance do I need to get? I found a probe on Amazon that's 1M Ohm and a capacitance of 18.5-22.5PF (below). I read something about trimming capacitors on scopes but ideally I'd like to start with the correct probes.
I also am a little confused about what the Hz rating is on a scope probe. The link below says "100MHz"..does that mean it's for measuring signals up to that speed?

Thanks in advance!
