Coupling Networks ENY22 and ENY41 have been designed to measure the asymmetrical (common-mode) RFI voltage of unshielded symmetrical telecommunication ports of EUTs in the frequency range 150 kHz to 30 MHz.

• Two-wire, four-wire and eight-wire networks;
• radio disturbance measurements in line with CISPR 22: 2008 and EN 55022: 2010 or CISPR 32 and EN 55032 (150 kHz to 30 MHz);
• ENY22 and ENY41 also for immunity measurements in line with CISPR 24 and EN 55024 (150 kHz to 80 MHz);
• compliance with CISPR 16-1-2
• adapter sets to meet standardized LCL requirements (55 dB and 65 dB) and to accommodate various telecommunications interfaces;
• high transmission bandwidth for wanted signal (100 MHz).
