Tom,
Afraid I don't have any help with this problem but a very warm welcome to the HP group. For those who don't recognise Tom's name and callsign, he is the brilliant designer of the DG8SAQ vector network analyser, VNWA.
I built an early kit and have had?a lot of fun and learned much. With retirement coming up, I will have time to explore a lot more of the amazing functionality Tom has developed it?and continues to do so?with new software releases. I urge anyone with any interest in VNAs up to 1.3Ghz to check out the Yahoo VNWA group.
