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.
