when i do sweeps while checking on scope i use two probes placing them
on each side of a part where i want to see freq/phase response and also check for resonances etc.
my generator goes to 40mhz, my scope goes to 100mhz so i check stuff up to 40mhz.
some times i get significant peaks in the rf range.
rearranging ground/screening, theese ringings can be dealt with and it clearly has effect on the sound.
however, depending on where i put the ground clips i get different response.
i usually use a ground buss point for the test point in question, so different ground points per probe, as long as the two test points doesnt share ground flow.
id like to get this right so i know when stuff is correct.
does my grouding makes sence?
should booth clips be grounded at all?
should they have the same ground point?
any tips are appretiated!!
