Embodiment Construction
[0023] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0024] Example of test system
[0025] like figure 1 The test system shown is composed of a clock tester, two optical fibers of equal length and same sex, a peer-to-peer transparent clock to be tested, and a computer with test and analysis software installed in the background. The two optical fibers are used to connect the corresponding ports of the clock tester and the peer-to-peer transparent clock to be tested. The reason why they are equal in length is to facilitate the calculation in the next step.
[0026] Embodiment of test special clock tester
[0027] Generally, the clock tester for the purpose of measuring the time synchronization accuracy can generally support the synchronization accuracy measurement of the PPS, IRIG-B, NTP and other output time signals of the device under test. The clock tester usually has a built-i...
