No result though we use serial to parallel converter the problem is with the constellation diagram

hello mathew, i could not find the solution.i tried it even in the version 13 the constellation diagram for QAM for 4 bits per symbol is same as the 2 bits per symbol.i think error in the software.

thank you all for your reply..i tried the suggestions posted by you people…i could see the phase change in the electrical signal but not in the optical signal…when i tried to modulate a NRZ data with optical sine wave all i could see is the electrical data phase has been changed and is being modulated(amplitude) on to the optical carrier but the phase of optical signal remains the same..actually am using version 7 and trying to design a optical QAM modulator in version 7. i would feel glad if i receive help from you people to design it.thank you
