Network Analyzer Software?

Anyone know where there is any FREE or very cheap screen capture, etc, type GPIB software for HP network analyzers, likethe 8720?

I wrote a free program to download s-parameters. Make sure you use the LabView 7.1 runtime as I have not tested it with new versions. If it doesn't work though I don't have time to mess with it now, but I tested it on several VNAs.

If you want a true screen capture then Plottergeist works well, but it's around S500.
