Hi Slimfish, being right is not a requirement for me as I have been wrong before. I am just trying to conduct a reasonable argument that we can all (including me) learn from. I have failed in my attempt to point out how T/Div in a DSO scope can impact the display amplitude roll-off and appear the same as band-width limiting would appear on a non-DSO scope. You have both ignored this argument as if I never made it.
I do appreciate your participation, but any future discussion without repeating the measurement on a Quad is futile. I don’t understand why Venarim has not repeated my measurement and reported his results. So all I can do now is wait until I get a Quad back into my hands and then take pictures.
I am surprised that another Quad owner has not responded with pictures of a 3.5Mhz square wave as depicted by a Quad. Oh well, I guess this just proves that no one with a Quad cares about this topic anyway. Thanks to both of you for participating.
