How to Set the BNC Output Line Mode as an Analog
Output
5 Press [Menu], move to <BNC Output> and press [OK].
6 Move to <V~P>, to choose an analog output signal, press Enter, and press
[Close].
Attenuator If you want to you use the analog output signal and your Tunable Laser
module has an attenuator installed, it is advisable to use <Manual Att.> Mode
and choose a constant attenuation value.

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 81640A/80A/82A/89A Tunable Laser modules 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 70 shows an example of specified and permitted wavelength range.
