Wave de-/embedding
In its original implementation, de-/embedding was calculated on the S-parameter
branch of the channel calculation chain. After applying factory calibration and/or user
calibration on the measured wave quantities, intermediate results were transformed to
the S-parameter domain. Before each
step, the S-parameters were
transformed to conductance (~ wave quantities), and vice versa afterwards.
The new "wave de-/embedding" remains in the wave quantity (~conductance) domain
and calculates all de-/embedding steps in one multiplication step, without unnecessary
matrix inversions. With "wave de-/embedding", the computation time does not depend
on the number of embedding and/or de-embedding steps but is constant.

Trace data flow
The diagram below illustrates the processing stages the channel measurement data
run through for each individual trace. Again, all stages are configurable.
