Configuring a DUT

Analysis from X nm to Y nm: the default range of the analysis. The
analysis limits can be modified later in the IQS-12004B Setup window.

Number of Ports: the number of ports, excluding the common port.

Port Number: In this list box, you select the port for which you will
configure the type and central wavelength. You can also use the
Previous and Next buttons to move from one port to another.

Port Type: In this list box, you select the type of port from the list of
available ports that you configured previously. Usually for a device, all
ports are of the same type, but this is not always the case; and the
software allows you to configure devices with different port types. For
more information, see Configuring an Optical Port on page 39.

Center Wavelength: You can specify a wavelength yourself (using the
Specified Wavelength option button), or select one of the ITU
wavelengths from the list (using the From List option button). The ITU
wavelength values correspond to the list defined in the Channel List
dialog. For more information, see Customizing the Channel List on
page 46.

ORL Analysis: Select this option to perform an ORL analysis.

The PDL Analysis section allows you to select options for PDL testing.

If you intend to export detailed IL results, check the
Keep IL traces for all states of polarization (4) box.

If you need to get the results from the polarization-dependent
wavelength analysis, check the
Polarization Dependent Wavelength box.

Note: These two options can also be selected when you set the test parameters.

For more information, see Preparing the Test Setup on page 49. If you omit
to check the boxes, you won’t be able to export the corresponding traces.
For more information on exporting, see Exporting Data on page 94.

Center Wavelength: The PDL value is taken at the central wavelength
for each port.
