It shows the composite voltage waveform, and the net current. Exactly what a Bird wattmeter would do. That's not what a Bird wattmeter does. A Bird wattmeter possesses a directional coupler. SPICE apparently does not. Is it possible to add a directional coupler to SPICE? If you know the Z0, the net voltage/current magnitudes/phases, it should be possible to use phasor addition/subtraction to obtain the forward and reflected components, just like the Bird wattmeter does. -- 73, Cecil http://www.qsl.net/w5dxp -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 100,000 Newsgroups - 19 Different Servers! =----- |
