Hi everyone I am trying to get impedance plots for a power bus board using HFSS 9. I performed simulations on the same geometry using the following 2 frequency ranges: 1) start = 1 MHz, stop = 200 MHz, step = 1 MHz 2) start = 1 MHz, stop = 1 GHz, step = 1 MHz But the impedance plots (1 MHz - 200 MHz) are different for both cases. Can anyone let me know the reason for that. I am using "fast" frequency sweep. Thanks --------------------------------- Yahoo!
