For some odd reason the Smith chart only accepts coordinate data and no
'common' (P)Complex data apart from frequency/time data. So, when you
convert data to XY (Re/Im) coordinate type of data, the Smith cahrt can
plot it.
In my opinion, the Smith-chart in VEE typically addresses signal-proccessing
engineering, and not typically microwave/RF engineering. Too bad! RF engineers
want a chart for plotting (P)Complex data and use either Z-Smith, Y-Smith,
polar or perhaps even rectangular or Carter 'grids/scales' or OVERLAY's
as Mr. Philip Smith, (the inventor) calls them. Marker read-out mode should
have the same choices, but not neccesarely the same setting as the 'overlay'.

Did you ever have it working under Windows 95 (Win32)? If not, and you've had
the card for a while, you may need a firmware upgrade. I had to send my card
back to ines for a firmware change and new 32-bit drivers.
