convertire file dataset in touchstone

Hi, everyone. I am wondering how to convert the Agilent ADS momentum database to TouchStone (*.sNp) or Citi files. Thanks.

If you do a s-parameter simulation by placing a black-box that will represent your momentum block (or directly itself) you can create touchstone or citifile format s-parameters.In this case, all ports should be 50 Ohm..

u can generrate the snp file , or even use ur layout as a schematic componnet with any number of ports

Thanks for all your reply. So where should I do the conversion, schematic window, layout window or data display window?

And which menu contains the operation? More details will be appreciated. Thanks.

1. You can do it either from schematic or data display window. Select "Tools -> Data File Tool" from the menu, a data file window will pop-up; then choose write data file from dataset; specify filename and file format as touchstone; select the dataset you want to export.

2. You may also write an equation in the data display window using the write_snp function. For example,

y=write_snp("spara.s2p", S, "My S-parameter file", "GHz", "MA", 50)
