论文摘要
由PTP白兔（PTP-WR）设备组成的时间传输链接可以以次纳秒精度传输时间。最初将白兔设备作为两种设备进行校准。校准的进展使单个绝对校准的PTP-WR设备成为可能。这使PTP-WR设备可以交换，而无需昂贵的原位端到端校准。 绝对校准是绝对校准的基础。它校准了内部时间戳与外部电时间参考平面之间的时间关系。在本文中，我们使用不同实验室校准的电气绝对校准的PTP-WR设备来检查链路时的电时间传输精度。
A time transfer link consisting of PTP White Rabbit (PTP-WR) devices can transfer time with sub-nanosecond accuracy. Originally White Rabbit devices were calibrated as a set of two devices. Progress in calibration makes individual absolute calibrated PTP-WR devices possible. This enables exchange of PTP-WR devices without the need for expensive in-situ end-to-end calibrations. Electrical absolute calibration is the basis of absolute calibration. It calibrates the time relationship between the internal timestamp and the external electrical time reference plane. In this paper we examine the electrical time transfer accuracy when a link is setup using electrical absolute calibrated PTP-WR devices calibrated by different laboratories.
