CISPR 22 ISN

CISPR 22 ISN

CISPR 22 defines ISN’s as specialized coupling decoupling devices used to measure the conducted asymmetric common mode radio interference voltages of an ITE. Fischer Custom Communications, Inc. ISN’s meet the requirements of CISPR 22 and we offer models for measuring conducted emissions on single, two and four balanced pair telecom ITE’s. All meet the requirements for Longitudinal Conversion Loss, common mode impedance, phase, decoupling isolation and voltage division factor.

Model F-071115-1057-1-09 can be used to test single, two, three and four balanced pair ITE’s. The new F-110729-1057-1-09 is for 4 active balanced pairs of CAT 5 and CAT 5e with a POE up to 500 miliampere per wire (1 ampere per pair).
