Fast Spectral Loss Measurement Application 3

Taking References

You can perform a reference measurement on a certain port by clicking the
corresponding New Ref. button. You can do this for any number of ports,
one after another. Each port that has been processed in this way will
display the timestamp of the reference sweep, the wavelength range used,
the port number that the reference was obtained at as well as the average
power of the reference sweep on that port.
Reference sweeps will be performed using the wavelength range and laser
power defined in the engine's main GUI. Power meters will be operated in
the range set in the Power Meter Reference section of the engine's main
GUI and the Port/Reference Manager. Auto ranging can be used for
reference sweeps as well as port-specific range settings (See "Range
Override on page 34" for details on how to use different ranges for
different power meter ports.).
