Hi Ivan,
After further discussion here, we are going to add the ability to specify whether you are using the TG 10MHz reference output, so it will disable this frequency correction. We think allowing the user to manually specify this is the best way forward. It will likely be a new checkbox in the TG control panel. Look for this in the next release.
Let me know if you have any further feedback or questions on the issue.
Regards,
A.J.
