Calibration Processes
Comprehensive offset functionality in the firmware
enhances the calibration of the optical path in various test
set-ups. There is an offset for the attenuation factor, and
an independent offset for the output power level, to
calibrate for losses due to the patch cords and connectors.
Additionally, wavelength and offset value pairs can be
stored in a table to compensate for wavelength dependent
effects in the optical path of the set-up. This allows you to
set the optical power level at your Device Under Test.
Calibration is even easier and more convenient if the
reference power meter and the attenuator are hosted by
the same mainframe: All power related offsets can be
determined by a firmware function that reads a value from
the reference power meter. The difference between the
power value read by the reference power meter and the
actual value of the attenuator is automatically stored as
the offset.
