Introducing the IQS-12004B DWDM Passive Component Test System
DWDM Passive Component Test System 9
Testing Procedure
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.
