2. Set the Optical Spectrum Analyzer
a. Set the Span to 4nm, Resolution Bandwidth to 0.1nm and the Sensitivity
to -60dBm.
(Waveln - > SPAN - > f 4 g - > nm - > BW.SWP - > f 0.1 g - > nm; Amptd - >
SENS Man - > f -60 g - > dBm)
b. Set the wavelength to the wavelength of the TLS.
(Waveln - > f xxxx.000 g - > nm)
3. Set the TLS:
a. Set the power to high power
#023 #003 #023+#003
8167A -4dBm -5dBm -5.5dBm -6.5dBm
8168D,E,F as stated in the test report
4. On the spectrum analyzer, set the Marker to the highest peak and select
delta. (Marker - > HIGHEST PEAK - > DELTA)
5. Using the MODIFY knob move the second marker to the highest peak of the
displayed side modes and note the delta between the 2 markers in the test
report.
6. Repeat list item 4 to list item 5 within the wavelength range of the TLS in
10nm steps.
