Like I say, my solution is to block any reflections from being
incident upon the source. But I have a question. Since we are
discussing coherent sine waves, it seems to me that any reflection
from the source impedance will become indistinguishable from the
generated wave. In fact, the present convention of generated power
equals forward power minus reflected power is designed to overcome
that very problem.


Hi Cecil,

So you DO want to perform this test?

Your presumption of coherency is false unless you engineer the
solution.

I got there first and made sure that wasn't gonna happen. :-)

Any random attempt has only a one in 360 chance of being correct
within one degree of coherent. This is simple interference math after
all. Most individuals would just notice a 10 degree error which would
boost your chances to slightly less than 3% - not very good coherency
wise.
