Oscilloscope Measurements

Well since I am in computer engineering at Ottawa U, I can get access to the equipment needed to a test like this.

My idea was:

Use a function generator with a splitter, with one terminal going to the first input of the oscilloscope using cheap 1$/ft cable, and the other terminal going to the second input using high end cable.

I could then experiment with different waveforms, as well as different frequencies to see if there is any difference in response at all in between the 2 cables.

Any thoughts on this? Mind you I'm not heading back until September, so this will have to wait .

interesting idea, I think someone may have done similar test before, maybe with a specturm analyzer, i don't quite remeber.

there definitely should be some difference among different cables, small but existing.
