Analysis Interface—Methods

Response

None

Note

This method starts the entire analysis process. You must have

set the starting and the ending power meter channels so the

results can be compiled and analyzed correctly, accordingly to

what is physically connected.
Once the analysis is complete, the results are available through

the IResults and the IAnalysis interfaces. IResults allows you to

retrieve the compiled traces for IL, ORL and/or PDL tests.
IAnalysis is used to retrieve a Single value as a result for IL, ORL,

PDL, central wavelength, flatness, bandwidth, polarization

dependency, etc.
If a calculation cannot be properly performed for a certain

property, the returned value will be a Double containing an

infinite value (1.#INF).
All retrieved data is for a given switch port. If you select a new

switch port, all results will be lost and new acquisitions must be

done before starting a new DoAnalysis method.
Each time the DoAnalysis method is started, all structured

results from prior analysis (available through the IAnalysis

interface) will be erased from memory.
