a Set the Sensitivity to -68 dBm.
b Set the resolution bandwidth to 0.5 nm.
c Set the center wavelength to OSA@max_SSE_power.
d Set the reference level to 0 dBm.
e Set the span to 6 nm.
f Record the spectrum.
10 Within the total spectrum, determine peak power
(power@SSE_peak) and note the value in the test record.
NOTE This is at the wavelength the TLS is set to for this measurement and
the OSA measures, respectively.
11 Calculate spectral SSE by using the following equation:
Spectral SSE = power@SSE_peak – ( max_SSE_power + 3 [dB/nm])
Note the value in the test record.
NOTE The measurements were done with a resolution bandwidth of 0.5 nm.
The additional value of 3 dB takes care of a resolution of 1 nm, thus to
get the SSE in [dB/nm].
