About them 'scope probes

They make roll-forming screws also. Google "tri-lobe screw". They're much better and more secure than self-tappers, and you can remove and replace them multiple times without weakening the thread.

Anyone wanting to store this list of TEKtronix probe characteristics should do it now. The link is no longer functional, I went to the Wayback Machine to locate it.

It has info on about 100 different TEK probes.

You got lots of answers in this 1.5 year old thread, but the group seems to have missed one explanation that might make sense to you.

Someone posted the bandwidth of two different probes in 1x mode, and that bandwidth was 6Mhz.

A square wave can be represented as an infinite sum of sine waves, one sine wave at the base frequency, and every odd harmonic of that base sine wave up to infinity.

See:

Your probes, when in 1x mode, are acting as low pass filters, with a

-3db point at the 6Mhz bandwidth of the probe. So for the input square wave, consisting of an infinite sum of odd harmonics, the 1x probe is filtering away most of the harmonics above 6Mhz.

When you low pass filter away most of the higher frequency harmonics that sum to create a square wave, what you have left is a *distorted* square wave.
