用fluke1800测试时，发现虽然显示PASS，但具体指标...

<p>屏幕上显示都打了对号，但看回波损耗和近端串扰的值都和<span style="FONT-SIZE: 14pt; FONT-FAMILY: 宋体; mso-bidi-font-family: &quot;Times New Roman&quot;; mso-ascii-font-family: &quot;Times New Roman&quot;; mso-hansi-font-family: &quot;Times New Roman&quot;; mso-font-kerning: 1.0pt; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA;">《</span><span lang="EN-US" style="FONT-SIZE: 14pt; FONT-FAMILY: &quot;Times New Roman&quot;; mso-font-kerning: 1.0pt; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA; mso-fareast-font-family: 宋体;">GB50312</span><span style="FONT-SIZE: 14pt; FONT-FAMILY: 宋体; mso-bidi-font-family: &quot;Times New Roman&quot;; mso-ascii-font-family: &quot;Times New Roman&quot;; mso-hansi-font-family: &quot;Times New Roman&quot;; mso-font-kerning: 1.0pt; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA;">综合布线工程验收规范》（</span><span lang="EN-US" style="FONT-SIZE: 14pt; FONT-FAMILY: &quot;Times New Roman&quot;; mso-font-kerning: 1.0pt; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA; mso-fareast-font-family: 宋体;">2007</span><span style="FONT-SIZE: 14pt; FONT-FAMILY: 宋体; mso-bidi-font-family: &quot;Times New Roman&quot;; mso-ascii-font-family: &quot;Times New Roman&quot;; mso-hansi-font-family: &quot;Times New Roman&quot;; mso-font-kerning: 1.0pt; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA;">版）有所出入，这怎么办？</span></p><p><span style="FONT-SIZE: 14pt; FONT-FAMILY: 宋体; mso-bidi-font-family: &quot;Times New Roman&quot;; mso-ascii-font-family: &quot;Times New Roman&quot;; mso-hansi-font-family: &quot;Times New Roman&quot;; mso-font-kerning: 1.0pt; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA;">有没有朋友了解这个规范，上面写的5e线级别C的最小回波损耗(dB)是15，代表低于15dB的都是不合格的吗？</span></p>

<p>你是怎么看的，发出来看看</p>

<p>不懂！不过我正在学，先坐板凳。</p>

<p>C级是指三类,D级才对应是5E的,所以没有看明白.</p>

<p>另外,还有一个,你有可能看错的地方,既然打了PASS的话,表示这个是符合EIA或者ISO的标准.&nbsp; 你是不是看到FLUKE显示那个值,因为FLUKE显示的比较粗的那个数值,&nbsp; 是指高于标准比对以后的数值. 你要看测试报告的详细的单项测试报告.他里面会显示一个最小指,这个是必须符合标准的.否则是不会PASS的.</p><p>所以我个人认为,你的是合格的.放心.</p>

<p>你选择什么标准进行的测试的？</p><p>选择不同的标准，测试值要求是不一样的！</p>
