Hello , i am trying to extract small signal Rout of a circuit with test source sweep.
For that i have defined and ac sweep of a test source on the output and to divide it by measured current in Iprobe.
i have done ac sweep for making making other dc sources gnd leaving Vtest only active, as shown bellow.
However i got an error as shown bellow,where i was wrong with my ac ,Vtest Iprobe method for finding rout?
Thanks.
