Adapter Removal is an extension of the 2-port UOSM calibration. It requires two addi-
tional reflection OSM calibrations with the adapter successively connected to port 1
and port 2.
Figure 4-9: Adapter Removal vs. UOSM
The obtained adapter characteristics are mathematically removed from the obtained
error coefficients. Uncertainties arising from a non-ideal characterization of the
unknown through almost cancel, whereas they add up in the UOSM technique. As a
consequence, Adapter Removal will provide more accurate results.
This holds up to a transition point where uncertainties due to connectivity issues
increase.
