³

Enable Auto-Range Filtering: This option is selected by default. When
selected, the software signal processing identifies and filters out any
invalid datapoints that sometimes occur at power meter autoranging
scale changes.

When not selected, no post process filtering is applied. A small
improvement in testing time will be observed. When the filtering is not
applied, data spikes between 0 and 0.030 dB may be observed at some
scale changes.

³

Use Simplified Method: This option is selected by default. It indicates
that the PDL simplified method will be used for each test. Simplified
PDL is faster than “standard” PDL (calculations do not take into
account the optical retardation of the polarization state adjuster), but
adds an uncertainty of about 5 % of the DUT PDL.

³

Folders: This feature allows you to specify paths for the different
databases.
