Hi,
I was wondering if somebody could explain to me why the scope input is usually 1MOhm to ground. I understand that this makes a 10:1 divider when using a 9MOhm probe, however what I don't understand is, why the division, why not use a high impedance input (GOhms) and not use any divider at all ?
Thank you for any explanation.
