Vector Network Analyzer for Phoenix
The block diagram for the Phoenix is so similar to that of a vector network analyzer that it would be a shame if we didn't include that capability in the Phoenix.
The idea is that we want to measure the vector that is described by having a length R and angle theta. The low pass filters give us 1/2 R cos( theta ) and 1/2 R sin( theta ), which are the Cartesian coordinates of that vector, just what we want.
This is only a starting point for the block diagram. We need to do some thinking about how to best integrate it into the Phoenix without compromising the present goals of the Phoenix. Post your ideas here!
