That statement bears no physical relationship to how the instrument
actually works (and "indirectly" won't get you off the hook either).
I was hoping someone would assert such. E^for is proportional to
Vfor which is what the Bird samples. H^for is proportional to
Ifor which is what the Bird samples. Within a 50 ohm environment
that yields forward power. Same for reflected power.
