CISPR 32 defines ISNs as specialized coupling decoupling devices used to measure the conducted asymmetric common mode radio interference voltages of an ITE. Fischer Custom Communications, Inc. ISNs meet the requirements of CISPR 32 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.
