Performance Tests Wavelength Accuracy

80 Agilent 81600B Tunable Laser Source Family, Fourth Edition

Switch on the TLS output.

6 Wait until the wavelength meter has settled then note the wavelength

displayed by the wavelength meter in the Test Record.

7 Set the TLS module to the next wavelength given in the Test Record.

8 Repeat step 6 and step 7 to the maximum wavelength value for the TLS

module:

9 Repeat step 4 to step 8 another four times.

10 Select the maximum and minum deviations from each repetition of the

measurements, and note these values in the Test Record.

11 Determine the Relative Wavelength Accuracy and Summary of all

Repetitions.

a Take the Largest Maximum Deviation and note it in the Test Record,

b Take the Smallest Minimum Deviation and note it in the Test Record.

12 Determine, and note in the Test Record, the

Relative Wavelength Accuracy, which is the

Water absorption lines For 81600B #130, #132, #140 and #142, some

wavelengths are set to odd values to avoid conflict with water absorption

lines.

Determining the Maximum and the Minimum Deviations

•The Largest Maximum Deviation is the most positive value (or the least

negative, if all values are negative).

•The Smallest Minimum Deviation is the most negative value (or the least

positive, if all values are positive).
