Rohde & Schwarz ENY22

Coupling Network Double 2-Wire.

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 according to CISPR22 (1997) and EN55022 (1998). In these product standards, this type of coupling networks is referred to as ISN (impedance stabilization network), whereas in basic standards they are called AAN (asymmetrical artificial network), Y-network (CISPR16) or CDN (coupling/decoupling network, IEC61000-4-6). In addition to emission measurements, ENY22 and ENY41 also enable immunity testing of the above-mentioned EUTs in the frequency range 150 kHz to 80 MHz according to CISPR24 (1997), EN55024 (1998) and IEC61000-4-6. They are tested and calibrated to CISPR/A/307/CD. ENY22 comprises two separate two-wire networks with two receiver ports in one box, whereas ENY41 includes one four-wire network.
