Dear optiwave team, what is the best (more precise) way to measure jitter (phase shift) for high bit-rate TDM?
If you are modulation scheme is NRZ/RZ on/off keying then you should try the BER Analyzer. It will calculate the Peak-to-peak jitter and RMS jitter value in the results section. Look at the component help for more info.
Thanks for your quick reply, Damain! Usually, more advanced modulation schemes are being used for high bit-rate, e.g. DP, QPSK, etc. Will BER Analyzer be useful for them?
You could observe it graphically like in:
In QAM there would be multiple levels, but it should be possible to just choose one crossing or take an average of multiple crossings.
Is it possible to useful Clock Recovery component to measure the phase shift and then estimate the jitter? Or Time domain visualizer will be more accurate?
I’m not sure how you would calculate the jitter from the phase shift. From my understanding the best way is to look at the eye diagram of a transmitted sequence.
OK, thank you for advice!
