Impedance stabilization networks (ISN, or with CISPR 16-1-2 called AAN: asymmetric artificial network or AN: artificial networks for coaxial and other screened cables) are defined for measuring of conducted common mode disturbances at information technology equipment (ITE) as required in CISPR 22. The ISN is placed between the equipment under test (EUT) and auxiliary equipment (AE) or load which are necessary for the operation of the EUT. The ISN establishes the common-mode termination impedance for the EUT’s telecommunications port during measurement. All internal parts fulfill the requirements of cat.6 or better and provide optimal transfer performance. The used internal cable has a symmetrical impedance of 100 Ω. The pin- arrangement of the RJ45 sockets meets the requirements of EIA / TIA 568B. ISN ST08 meets the requirements of CISPR 22, EN 55022, CISPR 32, EN 55032, CISPR 16-1-2 and EN 55016-1-2. Unlike the ISN T types for unscreened balanced lines the ISN ST08 needs no additional adapters for LCL setting.
阻抗穩定網路（ISN），在 CISPR 16-1-2 中被稱為 AAN（非對稱人工網路） 或 AN（適用於同軸及其他屏蔽電纜的人工網路），專為測量資訊技術設備（ITE）依據 CISPR 22 規範所需的傳導共模干擾而設計。
ISN 被置於受測設備（EUT）與輔助設備（AE）或負載之間，以確保測量過程中，EUT 的電信端口擁有正確的共模終端阻抗。
此設備專為進行電信設備的傳導共模干擾測量設計，符合國際標準，且無需額外配置即可進行精確測量。
