Description

CND 418TH8 is designed for coupling damped oscillatory waves onto high-speed unshielded symmetrical communication lines in accordance with Standard IEC/EN 61000-4-18 and can be applied to ISDN,10 MBit/s / 100 MBit/s / 1,000 MBit/s Ethernet test. Its powerful decoupling capability makes Auxiliary Equipment (AE)free from the influence of damped oscillatory wave and ensure the test repeatability. The maximum residual voltage is only 90 V left at AE port for 2 kV damped oscillatory test without using additional decoupling devices. Decoupling performance and transmission rate are stable. Compact size makes it easy to carry and use.

Features:

  • Applied to ISDN, 10 MBit/s/100 MBit/s/1,000 MBit/s Ethernet test.
  • Capable of test output to 1-pair, 2-pair or 4-pair communication line simultaneously.
  • Compatible with the output port of generators from other corporations.
  • No additional protection for AE is needed.
