hello
my circuit this, and work at 1MHz
i use typically probe at 1x
and scope have 1Mohm and 35p input impedance.
i have problem becaue my output's circuit should damped very very slowly but
when measure it, they damped fast.
in practice, i check my input signal genrator and inductance coupling and that's adapted with my simulation, and that is enough true.
i quess my probe had interference on with circuit and so measurment was wrong.
i ask to help me about. how can measure the capacitance and resistance of probe?
how can compensate effect of this parasitic element of probe??
how can measure accuracy??
how can reduce the resistance of probe??
