Introducing the IQS-12004B DWDM Passive Component Test System

DWDM Passive Component Test System 9

Testing Procedure

The IQS-12004B DWDM Passive Component Test System prompts the

operator to perform a series of steps, after which it controls the different

IQS modules to perform measurements on a device under test (DUT).

The testing procedure used by the system is outlined below.

³ You can configure different test parameters in the Setup step.

³ System calibration is performed the first time the system is used. It can

also be performed as needed. Calibration comprises three elements:

detector null measurement of power meters and the WRM,

wavelength response calibration, and return loss calibration.

³ IL/PDL and ORL reference measurements are required each time the

system is turned on and are recommended whenever there is a

significant change in environmental conditions.

³ The measurement scan(s) is performed. The insertion loss (IL)

measurement requires one scan, the IL/PDL measurement requires

four scans, and the ORL measurement requires one scan.

³ At the end of the scan(s), the results are calculated and analyzed. You

can view the results and print reports as required.
