Hello, i am trying to recreate the method described in the following post for calculating the output impedance, i put AC source as shown bellow to act as a probe , i added the coil to filter undesired signal , i put "iprobe" to get the output current , and "out" node for the output voltage.
when i tried to implement the expression for calculating the impedance , it gave me and error shown in the end.
where did i go wrong?/
Thanks
