4 Set the wavelength and power for each Tunable Laser module to the
values given in Table Table 15.
5 If you are using the Agilent 81480A, Agilent 81680A or the
Agilent 81640A Tunable Laser module:
Connect the output fiber to Output 2, the high power output.
Set <Optical Output> to <High Power (2)>.
6 Set the power meter channel of the HP 8153A to the following
settings:
a Set range to -60 dBm. Press Up or Down as required.
b Set T, the averaging time, to 500 ms.
c Set the l, the wavelength, to the same as your Tunable Laser
module, as given in Table Table 14.
d Select dB as the power units.
7 Press the DISP->REF hardkey of the HP 8153A.
8 Increase the wavelength of the Tunable Laser module and of the
Power Meter to the next value listed in the test record.
9 Measure the output power. Note the result in the test record
10 Repeat steps 8 and 9 for the wavelength settings given in the test
record.
11 From the measurement results calculate the difference between the
maximum and minimum deviation from REF and note the result as
the Flatness.
12 If you are using the Agilent 81480A, Agilent 81680A or the
Agilent 81640A Tunable Laser module:
Connect the output fiber to Output 2, the High Power output.
Set <Optical Output> to <High Power (2)>.
13 Set wavelength and power as given in Table Table 14.
14 Repeat steps 6 to 11.
