lol, I wasent talking about the high freqency, besides my scope is rated for 100mhz, way past any SMPS, I was talking about the 160/320v found on most primarys :/ and the fact id like to take diffrental signals on some components

Frequency should not damage a scope, even if it is a higher frequency than
the scope can be used to measure. Otherwise most scopes would be dead given
the amount of high frequency energy in the air. So unless you are doing work
with voltages higher than your scope is designed to work with you should not
need any kind of special probe. Most scope probes have a "10X" feature which
drops the voltage by a factor of ten anyways.
