1.我认为现在CISSPR 22中关于LAN在测试时的使用要求在某种程度上已经不合时宜了。对于LAN使用方式的规定是为了保证电信端口测量结果的高可靠性,特别是在不同实验室的测量结果之间比对时,这些规定尤为重要;要注意的是,这个要求是在标准以太网(10 BaseT)为主流技术时提出的。我还记得当时(3SPR/I/WG3的专家提出标准以太网(10 Base T)的IJAN数据流不会影响测量结果的报告。但是,对于现在的快速以太网(100Base T,1000 Base T)这个报告似乎已经不适用了。由于这个原因,CISPR 32草案中对LAN的使用方式提出了新的要求:“对于以太网接口,除了在接口支持的最大数据传输速率为10 Base T时可以在其典型的数据传输率下进行测试,否则需要在接口支持的最大速率的情况下
1. I think the current CISSPR 22 requirements for LAN use in testing are somewhat outdated. The requirement for LAN usage is to ensure high reliability of the telecom port measurements, especially when comparing measurements between different labs. These notices are important; note that this requirement is on standard Ethernet (10 BaseT) as the mainstream technology. I still remember that at the time (3SPR / I / WG3’s experts proposed that the IJAN data stream for standard Ethernet (10 Base T) would not affect the measurement results.) However, with the current Fast Ethernet (100 BaseT, 1000 BaseT) The report does not seem to apply. For this reason, the draft CISPR 32 puts forward new requirements for LAN usage: ”For Ethernet interfaces, except where the interface supports a maximum data rate of 10 Base T Test at a typical data rate, otherwise you need to test at the maximum supported interface rate
