Managing the Wavelength Shortlist
The FVA-3150 Variable Attenuator can test at many wavelengths. The
accepted wavelengths depend on the configuration of your unit. You can
store the wavelengths you use most often in a shortlist so you can quickly
access them. The shortlist includes up to 20 wavelengths.
Note: When switching to a new wavelength, the attenuator motor will reposition
itself to keep the current attenuation value for the new wavelength.
Refer to Technical Specifications on page 69 for more information on the
wavelength ranges that you can enter.
