Manual ORL
The OFI module can be equipped with the ORL function (option), which allows to make
an ORL manual measurement .
However, before making this measurement, the references have to be established once
the ORL tab has been selected on the OFI module or on the MTS 8000, in the S
page
The functions LTS, FOX and ORL can be selected at the same time on the
OFI module.
However, the Powermeter and ORL functions from the MTS 8000 cannot be
selected simultaneously.
Establishing a reference for an ORL manual
measurement
Two steps must be carried out to take a reference for an ORL manual measurement:
1 Power emitted reference: see
2 Zero ORL adjustment: see
Follow the order given above to take the reference. They are not two differ-
ent processes but two steps necessary to establish a reference for an ORL
manual measurement.
Establishing references is only valid for a specific module or function. For
example, the references for an ORL automatic measurement are only avail-
able for the FOX function (a new reference must be redone for an ORL man-
ual measurement.).
Moreover, the Manual ORL references performed with the MTS 8000 are
not valid with an OFI module.
