Hello !
I have a homework that i should do with pspice .
I don't know how to set the capacitance of a capacitor as the parameter of 'x' axis .
Is this possible ? If yes , please help .

 

LTSpice does it with ease. Note the {curly braces} and the .step param directive. Look at the netlist generated by LTSpice. That holds the key how to do it in PSpice (which I stopped using 20 years ago). Also note how I do an .AC analysis at a single frequency.

PSpice likely doesn't know how to do the plot; LTSpice does.

It seems to be useful . Thank you !

 

I think this can be easily done with pspice as well.
I had to connect high resistance to ground (to avoid floating node during operating point calculation).
