Coax cables and input impedances

This voltages have rise times of the order 500ns Roughly, for 50 Ω coaxial cable, the velocity of propagation of a signal is around 200,000,000 metres per second. So, in 1 metre, the signal takes ...

100 MHz probe and 200 MHz probe show very different waveform on 1 MHz signal

A 1 MHz sine wave is not the same as a 1 MHz square wave - the most important part of what you're measuring and interested in here is actually the "edge rate", or the rise and fall times. ...

100 MHz probe and 200 MHz probe show very different waveform on 1 MHz signal

The signal under test is 1MHz, and as far as I can see, both probes are showing that signal correctly. What you are looking to see on the edges, is less than 20ns. A signal with a period of 20ns has a ...
