This looks like a nice little analyzer. I have used the AD8302 and it
does a decent job within its 60 dB range limitation, which should be
enough for most measurements. Since it has its own oscillator, I assume
the levels are permanently set to maximize dynamic range. Note that it
is a one port device, however, so it can't measure DUT input vs. output
parameters such as gain and phase and other parameters between input and
output.

They may get another one going, but it was a lot of work and I wouldn't
count on it. There's also a VNA project underway in Italy, but I can't
recall the details.
The Italian VNA project is at

After much internal debate, mainly because of available time, I have placed an
order for a built one (shame!). I will let the group know how it performs when I
get it.
