Appendix A Specifications
Jitter and Wander specifications
Measurement filters
Measurement filters are defined per ITU-T Recommendation O.172 (04/2005).

1. Supported on MSAM only.
The maximum wander measurement time is only limited by the available hard disk
space. However, you can only perform wander analysis (MTIE/TDEV) for the first 8.64
million samples of the measurement.
