134 Agilent 81600B Tunable Laser Source Family, Fourth Edition
11
Determine SSE of the Tunable Laser output signal by using the
maximum value at its border:
a Note the power measured at:
OSA_
λ_center - 1 nm
b Note the power measured at:
OSA_λ_center + 1 nm
c Determine the larger of these two power values and note it as
SSE_power_λTLS_max.
Record all the power values in [pW], where 1 pW = 10
-12
W.
d SSE_power_λTLS_max= ________ 10
-12
W = _______ pW
12 Determine the Total SSE power, power_total_SSE.
Add the values of OSA_noise and SSE_power_
λTLS_max:
power_total_SSE = OSA_noise + SSE_power_
λTLS_max
= ___________ 10
-12
W = ___________ pW
13 Calculate the Total SSE in [dB] using the following formula:
Make sure that all power values are entered in the same units, for example
Watts, W, or picowatts, pW. This ensures that the equation will give Total
SSE in decibels, dB.
14 Note the result in the Test Record:
Total SSE = ________________ dB
