Homework Help: Input Signal in P-Spice

  1. Oct 8, 2007 #1
    1. The problem statement, all variables and given/known data
    I need to simulate a certain circuit in p-spice, and get the transient response of a capacitor and a zener diode. I know how to do everything, except for the source voltage. The requirement is that the voltage has to be:

    [tex]V_{in} = 10 sin (2\pi\times 50 t)[/tex]

    I don't know how to do it.

    2. Relevant equations

    3. The attempt at a solution
    What I did was I just took the part called VAC, which is a simple AC source with a DC offset option. I set the AC parameter to the input voltage above, and DC offset to 0. However, I put a voltage marker right after the source, and instead of getting a sine wave, I get nothing (0 voltage).

    If it helps, I attached the circuit I need to build and simulate.

    [tex]R_1 = 10 \Omega[/tex]
    [tex]R_2 = 100 \Omega[/tex]
    [tex]C = 100 \mu F[/tex]

    It says the zener voltage is 6 V. It says nothing about D1, so I guess I will assume it is an ideal diode.

    If anyone could please show me how to make any signal I want in P-spice, or at least just the one for this problem, it would be greatly appreciated.
