EEVblog #652 - Oscilloscope & Function Generator Termination Demo
Dave explains a big trap in high frequency measurement with your oscilloscope.
Based on a viewer request, Dave demonstrates how to incorrectly and then correctly measure the signal output level over frequency of your function generator using your oscilloscope.
Some whiteboard transmission line theory, reflections, termination, group delay, phase delay and assorted stuff is thrown in as well.

Check out Doug Ford's Oscilloscope probe article which explains a lot of this stuff, and why x10 probes are better than x1.
