All-

Hypothetically, would it be plausible to build a VNA with custom synthesizer/detectors and the 85047A test set? There seems to be plenty of room inside the box to add the other components. Also, is the 85047A the best choice, assuming that the desired frequency range is 1 MHz to 4 GHz?

Thanks-

Jim
What would be your idea - create a unit controlled via USB and have a
PC as the interface? Like this sort of thing?



That would seem to me the only way you could fit everything inside the
box, as you are not going to fit a screen on the test set.

The hardware design, testing, software development etc would suggest
to me this would be a very long term project. I think trying to base
it on something pre-existing like the test set might slow developement
more than help.

Designing a VNA for 4.2 GHz is not going to be easy.

Rather you than me!
