How to Set the Wavelength

There are three ways to set the wavelength of the Tunable Laser.
• You can set the wavelength (λ) directly,
• You can set the wavelength from a base wavelength and an offset in the
frequency domain, or
• You can set a wavelength range for the instrument to "sweep".

Wavelength Range

Every Tunable Laser module has a specified wavelength range. This range
is available for all Tunable Laser modules. See Appendix C of the
Agilent 81640B/42B/72B/80B/82B & 81480B/82B Tunable Laser User's
Guide to find your module's specified range.
Every Tunable Laser module has a permitted wavelength range. This range
is greater than the specified range. The permitted wavelength range varies
for each Tunable Laser module. You can set the wavelength to any value
within the permitted wavelength range.
Figure 68 shows an example of specified and permitted wavelength
range.
