10 At the Return Loss Module, press [TermCal] in order to calibrate
the Return Loss Module at termination condition.
11 Connect the open end to the Power Sensor Module.
12 Enter the Power reading [P] on the Power Sensor Module as
[FPDelta] on the Return Loss Meter. Make sure you enter the sign of
this value correctly.
13 Note the Return Loss reading as the Return Loss result into the test
record.
Relative Uncertainty due to Polarization
(Optional Test)
N O TE
The performance test "Relative Uncertainty due to Polarization" is
optional, since the polarization is given with the production of the unit
by mechanical and optical cavities and stays unchanged by normal use
of the sensor module.
Below, you will find the test setup to verify the relative uncertainty
due to polarization of the sensor module. Generally, during this
measurement-procedure the tunable laser source is swept through a
predefined wavelength range. After every wavelength step, a single
PDL-measurement is made, where the polarization controller
generates all different polarization states. The highest PDL value is
taken as the "relative uncertainty due to polarization". The low output
power path of the coupler is used to monitor the power stability of the
setup
