Home Tube DIY Asylum

Do It Yourself (DIY) paradise for tube and SET project builders.

RE: To a point.

"General rule of thumb for measuring equipment is 5x the measured bandwidth. So to accurately measure a 20khz square wave, your scope needs at least 100khz of bandwidth."

Not to nitpick your comment, but for accurate visual analysis of square waves, 10X is a better rule. We have scopes where I work with bandwidths of 1.5 gHz, and we make (among other things) devices that output TTL-level square waves to beyond 200 MHz. I've tested 80 MHz square waves (one of our "standard" frequencies) with both a 400 MHz scope and our 1.5 gHz scope. There's a marked improvement with the higher frequency instrument.
