Acquiring Zero Loss Reference for a Device
For simple passive optical devices, only one channel is required. To characterize a device:
1. Select the processing mode, insertion loss, or PDL. Perform a zero loss measurement for
the selected channel, connecting the system, as shown in Figure 78.
Figure 78: Acquiring a Zero Loss Reference
2. Connect the device using the same jumpers as used for the zero loss reference. Follow the
procedure, outlined in the Measuring Insertion Loss section for IL measurements or the
Measuring Polarization Dependent Loss section for PDL measurements, to acquire and
display the trace.
Measuring Insertion Loss of a Device
To measure the insertion loss of a device:
1. Connect the DUT to the SWS as shown in Figure 79. Follow the instructions provided in the
Using SWS Software section to acquire and analyze an insertion loss trace. The section
contains an explanation of the types of markers that can be placed on the plot, the various
types of analyses that can be performed on the data, and the ways in which the plot can be
manipulated.
