* there is a case where tolerance of Sync rise time is added to Sync width tolerance.
* Measurement of Burst time length is made between
the Burst start point which is defined as the zero-cross point,
preceding the first half-cycle of the sub-carrier where Burst amplitude becomes higher than 50 % level and
the Burst end
