The R&S®ENY21 and R&S®ENY41 coupling networks have been designed to measure the asymmetrical (common-
mode) RFI voltage of unshielded, symmetrical
telecommunications ports of EUTs. The measurements can be performed in the frequency range from 150 kHz to 30 MHz and are in line with the CISPR 22: 2005 and EN 55022: 2006 product standards.
The R&S®ENY21 and R&S®ENY41 can also be used for immunity measurements of the EUTs. These measurements can be performed in the frequency range from 150 kHz to 80 MHz and are in line with the CISPR 24, EN 55024, and IEC 61000‑4-6 product standards.
The coupling networks are tested and calibrated in line with CISPR 16-1-2. The calibration data supplied refers to a symmetrical impedance of 100 Ω.
