Ok. Thank you very much for helping.
And I have a one question. May I ask you?
Because now I use the design of Raman scattering separated channels inside the optiststem library. During the analysis, I added the Ideal Demultiplexer but the signal shown on the analyzer and meter for each channel is same. The signal shown is the output of the first channel in the input which is used as the pump signal.
What is the problem? Is it my setting wrong at the Demux part?
