OK, my query on getting better isolation did not get any replies. So How about this. What kind of test fixtures do you use? For VLF through HF they should be reasonably simple, right? but to get the error factor down, what is your method.
Yes, we can calibrate out a lot, but it does not address the cross coupling isolation for really good measurements. I have really good ones for VHF / UHF and do get the isolation down to a point where I see >-50 db unloaded data. There are a lot of illustrations on these kinds. What are your ideas? Thaks.
