Has anyone here had good results from any of the non-MFJ impedance meters? I
have an MFJ-259 and 269 and they are handy to have but not very accurate in my
experience. I have made lab measurements against these and the results are
not as good as I'd like.
At work I designed a network analyzer for production S21 measurements and it
beats an Agilent 4395A VNA for accuracy. I'm tempted to adapt it for S11
measurements but I'm a bit lazy. Some other time.
Ten Tec has a unit that looks nice, I think it uses the Analog Devices AD8302
gain/phase detector. This isn't the best thing in the world but it would be
good enough for my uses. But with a price of $600 I'd like to find something a
bit more reasonable.
