Spice power source?

I'm kind of stuck on making a 50 ohm power source in Spice (instead of just using the voltage or current sources). I would like to make a

50 ohm power source with a Pout of 0dBm. I realize I have to use the Spice voltage source with a series 50 ohm resistor, but do I set the voltage source to 632 mV or 316 mV in order to get a 0dBm Pout (in a fifty ohm system)?

Thank You,

Bill

I assume you mean you want 0dBm into a 50 Ohm load from a 50 Ohm source, so you use 632.46mV for VP

I love to cook with wine.      Sometimes I even put it in the food.

I was a geek named "James" until I met my wife-to-be... I then became "Jimmy" ;-)

It's hard to see Jim as a "James"! Too dang formal.
