Increase λ, the output wavelength, of the TLS module and of the power
meter to the next value listed in the Test Record.
For the 81600B #140, #142, and #142 #003, some wavelengths are set
to odd values to avoid conflict with water absorption lines.
11 Measure the change in output power (in dB) and note this value in the
Te s t R ec o r d.
12 Repeat step 10 to step 11 for all wavelength settings listed in the Test
Record.
13 Determine the maximum deviation and the minimum deviation from
REF and record them in the Test Record.
14 Subtract the minimum deviation from the maximum deviation and
record the result as the Flatness.
