[Wei-Da Yang, Li-Quan Zhang, Qing Cai, Jun-Gang Li] CN Shenzhen A variable spacing device includes a support member, a driving member, a number of movable graspers, a limiting block, and a pushing block. The movable graspers are slidably mounted in a line on the support member. Each movable grasper grasps a workpiece. The limiting block is mounted on the support member and arranged in parallel with the pushing member. The limiting block defines first sliding grooves having a length gradually decreasing along a same direction. The pushing block defines second sliding grooves having a length gradually increasing along a same direction. Each movable grasper moves within a corresponding one of the first sliding grooves and a corresponding one of the second sliding grooves. Two sidewalls of each first sliding groove and two sidewalls of each second sliding groove resist movement of the corresponding movable grasper.

This testing method uses the field of correction field (correction Field) in the IEEE1588 message to “magnify” the response of the slave clock DUT to the abnormal message stimulus, and realizes a real-time closed-loop detection to efficiently verify whether the message processing logic of the slave clock DUT follows the IEEE1588 protocol.
