FreeLists / si-list / [SI-LIST] Problem with HFSS 9

[kundanchand chand <kundanchand@xxxxxxxxx>]

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
