The 60 MHZ specification on your
scope means its vertical amplifier and display will start to degrade
at 60 MHZ or higher in frequency.


No. It is 3dB Bandwidth. Degrade will start earlier. You will have lost
half power or in voltage around 30% of the signal.


Therefore using a probe with a 60
MHZ rating will allow you to realize all of your scope's capabilities.


There is also a capacitance specification that should match. It is
however unlikely that it should not. Go ahead with the 100MHz probes if
you get them at a fair price.
