Note
In our application every few million measurements an erroneous value that is off by ±4 ns was observed. These outliers look like not following a Gaussian distribution (see for example figure 3 and figure 6 in the TDC performance report).
In July 2013 it has been confirmed with ACAM that:
- such an error could statistically be coming from the TDC-GPX chip in I-mode;
- none of the other TDC-GPX I-mode users have reported such an issue; as most users are filtering their measurements this may be hiding the issue.
