I found a lot of references to estimating the uncertainties in
measurements derived with three cornered hat. What about for arbitrary
N sources and N(N-1)/2 pair-wise measurements? There must be some magic
term to search for.

Mark,
When you refer to "30 dBc", what is that? Is it the eb/n0 value? If so,
with the XLi's
behavior as you report it, your scheme would fail over most of the useful
signal range.
And, it will probably differ from setup to setup of the HW, depending on
all the parameters
that have already
