Hi Fangood,
if you have ADS, use the TDR function in the Data Display. It's a mathematical
function that fouriers and windows the data to get a step or impulse response.
The data can be displayed in Impedance profile directly.
You can put the function as EQN into the data display, or put it directly into
the trace expression (that's my favorite way).
Just double-Click on a trace and click on "functions help". Then click
"Measurement expression Functions" and browse for "TDR".

Betreff: [SI-LIST] How to convert S parameter to TDR waveform?
hello everyone:
The question is How to get TDR based on S parameter. One easy way, ADS
can bulit up a transient response simulation with S parameter block.
The other way is to use IFFT, but if I do IFFT with S11, the result is
impulse response or step response. I know if I do IFFT with S21, I can get
impluse response. Dose anyone have the code to convert S11 to TDR? I want to
study it, and thanks a lot for help.
Good luck to all.
