Synch Persistence Target (Custom IQ)

Synch Persistence Target allows the user to tune the algorithm for higher frequency lock range or higher constellation lock consistency. Values closer to 0 optimize towards higher frequency lock range while values closer to 1 optimize towards higher constellation lock consistency.

If the analysis synchronization is not stable:

Check that filtering specified is correct
Check that constellation positions are correct
Turn off “Coarse Frequency Estimation Enable”
Try the equalizer (Filter Tab)
Try varying the Clock Adjust parameter
Increase the Synch Persistence Target value
Increase the result length (Format tab)
Use pattern search if a specific repeating pattern can be identified
