I have recently upgraded our PC to Windows 7 and have found that a previous COM programming is not performing the correct function as it did in the past. I ma experiencing this on 5242B,5242A PNA-Xs with Windows XP / Windows 7 OSes.
Using the Agilent835x library, the following code
Does not set port 1 (or 2 if I change that to a 2) to use a user defined S2P file. It actually sets it to use circuit model.
Has anyone else ran into this?
