introduction：
NTFM 8131A is the latest ISN impedance matching network produced by Schwarzbeck, Germany, and is sold and quoted by Shenzhen EUTTEST. "Impedance stabilization network NTFM 8131 A", also known as T-ISN, is used to measure asymmetric interference voltages on symmetrical data or telecommunications lines. Since 2002, T-ISN has been used to measure the asymmetric interference voltage specified in EN 55015 (electrical lighting equipment). In addition, it can also be used for measurements according to CISPR 32. Compared with the widely used T—ISN, NTFM 8131 A is designed to withstand 400 V AC with a maximum current of 3 A.
