Hi Damian,
thank you very much your reply.
My purpose is generate 4 APSK signal according to a paper.
about two BPSK: there are 2 MZM in 1026edit.osd file. I wanna to check output constellation for each MZM.
I have one paper about this:
“The two sub-modulators of the DPMZM are biased at null point and driven by 10G Data1 and Data2, respectively, to generate two BPSK signals with unequal amplitudes. The two BPSK signals are then constructively added by adjusting Bias-C such that a 4APSK signal can be obtained.”
So, how to check BPSK signals with unequal amplitudes in 1026edit.osd file?
I’m looking forward your reply.
