Re: USING THE NANOVNA AND SAVER TO MEASURE CM ATTENUATION THROUGH CMCs


 

Hi Dave

Thanks for the procedure;Exactly what I want to do. It's generally clear but as a 'new driver' of the VNA in my Santa sack, I have a couple of comments / requests
1 SAVER- what is this, where do you get it, how do you use it?....reference essential
2. Stand-alone Procedure needed.
3 Test fixture, which looks ok for HF, could have significant stray coupling for use at v/uhf- a VHF CMC is the first project here. A plot of the test fixture open cct coupling /loss up to the freq. limit of the vna would be helpful. Converting everything to BNC is a GOOD idea.
4 If you cite previous measurements, you should reference where they are, or include them
5 USA specific antenna wire types - not helpful to a world-wide audience, again, reference desirable.
6 I'm a little surprised that both wires at each end of the CMC are not connected.

Keep up the good work
