Set the pulse light output level
(Low, Normal).
Explanation
Pulse Light Output Level
The AQ1200x/AQ1205x consists of models that make measurements by using 1625 nm or 1650 nm
optical pulse wavelengths. Even though these differ from the wavelength for optical communication,
if communication light is present in the optical fiber (the fiber is in use), the communication itself may
be affected. If a filter that blocks measurement light at 1625 nm or 1650 nm is not attached to the
optical fiber that you are trying to measure, you can perform measurements without affecting the
communication light that is present in the optical fiber by lowering the pulse light output level.
Normal: Pulse light is generated at the maximum power.
Low: Pulse light is generated at low power.
You cannot set the pulse light output level on the AQ1200A or AQ1205A.
