Synch Persistence Target (Custom IQ)
allows the user to tune the algorithm for the best balance between better frequency locking and better synchronization. Values closer to 0 optimize towards higher frequency lock range while values closer to 1 optimize towards higher constellation lock consistency. If synchronization is not stable, increase the Sync Persistence Target value by moving the slider toward the right.
Other things to try 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 result length (Format tab)
- Use pattern search if a specific repeating pattern can be identified
