Procedure
• Perform the peak search and bottom search within the range of parameter Test_
Band/2 by centering on the reference wavelength λi of each channel, and obtain the
peak level (LP’i) and the bottom level (LB’i).
• Use the peak level (LP’i) and bottom level (LB’i) obtained in the above procedure to
obtain the ripple from the following equation:
Ripple = LP’i − LB’i
