Wavelength Accuracy Performance Tests
Agilent 81600B Tunable Laser Source Family, Fourth Edition 87
8 Set the wavelength of your TLS module back to the reference
wavelength and wait until the wavelength meter has settled.
9 Measure the wavelength using the Wavelength Meter and note the
result in the Test Record.
10 Repeat step 7 to step 9 for all the wavelength settings given in the
"from wavelength" column of the Test Record.
11 From all wavelength measurements pick the largest measured value
and the smallest measured value.
12 Calculate the wavelength repeatability by subtracting the smallest
measured value from the largest measured value.
