Thank you Damian Marek.
Actually I am using Matlab component and transferring my analog RF signal to matlab for digitizing there. But the problem here is how can I import analog signal from optisystem? Should I use SignalTransfered=InputPort1.Sampled.Signal for transferring RF signal from optisystem into matlab?
My second point is, the InputPort1Sampled.Signal structure stores values in array, are these the amplitudes of RF signal at sampled times?
Kindly help.
