And tough to find any substantive information on the hardware design. I
poked around for a few minutes, but all I was able to find was software
user manuals, but no hardware description.
I assume that it's the usual 2 port, 1 direction thing.. A DDS for the
RF source, and some sort of dual channel detector with directional
couplers or a bridge on the output port.
What would be interesting is to know what detection method they're using..
