4 Connect the fiber to the low SSE oupout, Output 1.
Set <Optical Output> to <Low SSE (1)>.
5 Make sure the optical output is switched off.
6 At the 81624A/B:
a Zero the 81624A/B. Select <Menu> then <Zero>,
b Automatic ranging is set by default
c Set the Averaging Time to 500 ms,
d Select <dB> as the power units,
e Set λ, the wavelength, to the same as the TLS module, as given in
step 3.
7 Switch on the LowSSE output of the TLS.
8 Note the power value displayed by the 81624A/B in the Test Record.
9 At the 81624A/B, select <Menu> then <Disp → Ref>
10 Change the power setting of the TLS to the next value given in the Test
Record.
11 Note the (relative) power displayed by the 81624A/B as the “Measured
Relative Power from start”.
12 Calculate the "Power Linearity at current setting" as the sum of
"Measured Relative Power from start" and "Power Reduction from
start".
13 Repeat step 10 to step 12 for all power levels listed in the Test Record.
