O/O Measurements
A limited variety of O/O measurements can also be made where both the
modulator and detector responses have been de-embedded. Optical match is
in no way corrected and the fiber (including patch cords) used in the
measurement will not be corrected (but normally have no notable frequency
response anyway). The dialog is very similar to that shown for E/O and O/E
measurements (see
below). Currently, O/O measurements are
supported by VectorStar.
One must now either provide two .s2p files (one for the modulator and one for
the detector) or measure one on-the-fly (much like how the modulator was
characterized for the O/E measurement process). In some sense, this
on-the-fly characterization is like an O/O normalization calibration step. In
any event, at the conclusion of the process, the reference planes are both in
the optical domain and an O/O annunciator will be displayed.
