Repeat these two steps until absolute maximum on 8153A display is
reached

Note the displayed value on 8153A in your test record in the column “Power after
DUT" for the associated wavelength.
8
Repeat list item 6 to list item 7 for the wavelengths between 1480 to 1570 nm in
steps of 10 nm, always setting the 8168A and the 8153A to the required
wavelength for each setting.
9
Repeat list item 6 to list item 7 again for 1470 nm to ensure stability of
measurement setup. If your measured value is more than .01dB off the previous
value, you need to fix your setup and repeat list item 3 to list item 8.
