Check with Polar.

They manufacture TDRs and they have an excellent field solver for designing 
the board construction.

Best regards

Subject: [TN] controlled impedance


TechNetters, can anyone assist me with understanding controlled impedance 
measurements on unpopulated PCBs? I have looked at TM-650, method 2.5.5.7. 
If anyone with experience in making controlled impedance measurements could 
contact me, I would appreciate it greatly.

Louis
