Measuring Laser Separation
It is often important to measure the wavelength and power separation
between multiple laser lines. This is especially true in wavelength-divi-
sion-multiplexed (WDM) systems where channel spacing must be
adhered to. The Agilent 86120C can display the wavelength and ampli-
tude of any laser line relative to another. In fact, the following types of
relative measurements can be made compared to the reference:
Relative wavelength, absolute power
Relative power, absolute wavelength
Relative wavelength and power
