The jitter tolerance of the bare device in T1 mode exceeds the capabilities of the
measurement equipment. This behavior is independent from frequency offset or PLL
gain.
Using the jitter attenuator slightly reduces the jitter tolerance to a level which can be
measured. All requirements are fulfilled.
