TESEQ ISN T2A 阻抗稳定网络

用于一对非屏蔽平衡线对完全符合CISPR22, Ed5.2:2006 以及EN55022:2006 (IEC/CISPR22:2005 修订版) 中关于三类线和五类线的要求RJ11和RJ45接口，线序可调可以用做IEC61000-4-6标准传导抗扰度的CDN

产品特点：阻抗稳定网络（ISN）是依据CISPR 22（EN 55022）标准对信息传输设备（ITE）的共模干扰进行测试的耦合/去耦网络，ISN放置于被测试设备（EUT）与辅助设备（AE）或EUT的负载之间。在测试期间，ISN可看作是给通信端口提供了共模终端阻抗。ISN T2A是为测量符合平衡线对而设计的。其原理在CISPR 22-D2-Ed.5.2,2006和EN 55022，2006年9月（IEC/CISPR 22:2005修订版）中有规定。ISN T2A含D-Sub-25连接器的基本网络(ISN T200A)和专用适配器组成。这套适配器包含两个LCL适配器安排线路并可以实现EUT端所必须的3类和5类线纵向转换衰减（LCL），一个连接适配器为AE端安排线路。

The ISN is placed between the equipment under test (EUT) and the auxiliary equipment (AE) or load which is necessary for the operation of the EUT. The ISN establishes the common mode termination impedance seen by the ecommunication port during measurement. The ISN T2A is designed for measurements on one unshielded balanced pair. The principle drawing is shown at D.2 in CISPR 22, Ed.5.2, 2006 and EN 55022 Sept. 2006 (IEC/CISPR 22: 2005 modi? ed). The ISN T2A consists of one basic network (ISN T200A) with D-Sub-25- connectors and special adapter sets. A set of adapters consists of LCL adapters to realize the longitudinal conversion loss (LCL)- requirements for the EUT-side in relation to the used cable category (cat.3, cat.5) and a connection adapter for the AE-side.Frequency range: 150 kHz to 80 MHz Line parameters: 1 pairPower rating (EUT- and AE Port) AC max. voltage (line to ground): 63 V DC max. voltage (line to ground): 100 V Current max : 400 mA Test voltage: 200 VDC, 2 secCommon mode impedance (EUT Port) 150 kHz to 30 MHz: 150 ? ±20 ? 30 MHz to 80 MHz: 150 ? ±40 ?Phase angle (EUT Port) 150 kHz to 30 MHz: 0° ±20°Coupling path (In/Out-port/EUT) Connection: BNC 50 ?
