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.
The question was would a 100 MHZ probe work with a 60 MHZ scope. The
asker claimed to be a beginner. I made a general comment about why it
would. I saw no reason to muddy the waters by talking about half
power points and 3dB bandwidths. Trying to make it simple.
