How to Avoid Excessive Power?
If the text EXP is displayed in power of a Tunable Laser channel, you have
set an output power level that is larger than the laser diode can produce at
the selected wavelength.
To avoid this you can:
• reduce the optical output power,
• click Set P
power for the selected wavelength.
• click Set P
selected wavelength sweep.
What is a Wavelength Sweep?
A wavelength sweep is performed when the instrument changes the
optical wavelength of the optical output across a user-defined wavelength
range. You can use a wavelength sweep to measure the
wavelength-dependent loss of an optical component.
How to Set the Wavelength Sweep?
The wavelength sweep can be set up through the Sweep VIEW tab.
