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.

4.1.5.2

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.
