[Urgent] How to Import txt file into CST MWS

[kela3kela]

Dear Members

I have a S-parameter txt file containing two columns. How can I import this txt file into CST-MWS so that I may plot the S-parameters inside the electromagnetic simulator.

Awaiting replies,
Regards

Two columns?
You should have three columns: frequency and complex reflection factor (real/imag or dB/phase)
If you only have frequency and magnitude, you can't use the data for simulation.

If your file has these 3 columns, it can be easily used as Touchstone file by adding the corresponding header line:

Show your file.

@volker:
File attached.
This file is exported originally from CST MWs. I need to modify something and see its effect again by importing into CST.

Your file has no complex data, just magnitude. It is not possible to use this in simulation.

If you want to have it in a plot, to compare to other results, see here:

Thank you for the clarification,
But can you explain the procedure if I do have snp file..How can I import that?
