Hi, Experts:
I use Tek TDS8200 Oscilloscope to measure Differential impedance of
PCB
fro compliant HDMI Spec. At final result we use a 200 pSec and Centered mode
filter function
to filter the sum of two odd mode impedance, the equation as :
Filter (channel 1 + channel 2).
Now, I want use Ansoft Nexxim to simulate this measurement, I use
50*(V(Port) /(0.25-V(port))) and 50*(V(Port_N) /(-0.25-V(port_N)))
to get two odd mode impedance, respectively. but how to implement the
the sum of two odd mode impedance with 200ps fileter function in Nexxim?
Best Regards,
Yardala
