EEVblog #453 - Mysteries of x1 Oscilloscope Probes Revealed
Why people recommend it
Dave Jones explains how passive x1 scope probes work and why their bandwidth is far lower than x10; cited when fast signals look wrong through a switchable probe.
Watch for: low bandwidth in x1 mode
In their words
From reading Input Impedance of an Oscilloscope and the video EEVblog #453 - Mysteries of x1 Oscilloscope Probes Revealed, I don't understanding why we add these capacitors in the probe circuitry and make things more complicated.

Maybe you have already seen this but if not, have a look at: [video] probably in your case what is bugging you is that the connection from the probe to the scope is not a transmission line and/or it is but it might not be properly terminated.
