The Treachery of Oscilloscopes — Analog Oscilloscope Bandwidth Considerations
My friend Alan (w2aew) has done a great little video about bandwidth factors in scopes. He writes:
I’m often asked by hams and hobbiests – I want to buy an oscilloscope, what bandwidth scope do I need? I usually answer – buy as much as you can afford, even if you are working on low frequency circuits. This video shows an example of why. Even simple audio circuits might have some hidden evils!

BTW – I posted a followup video which answers a few questions I received from this video, plus presents some of the considerations for using a digital scope on this same signal. http://www.youtube.com/watch?v=IcrnXRbkLpc
