To view data as a smith chart:

1. Take s-parameter data and send that to a calc button to extract only the S-parameter you are interested in i.e, S21 etc.
2. Send this data ( it is now just a pair of complex numbers ) to a local variable ( Data save buttons can not save more
than one data item, so they cannot handle complex data pairs ) .
3. Open the view for the local variable and select Smith Chart as a display.
