Com-Power ISN - EMC Testing
ISNs - Impedance Stabilization Network
Com-Power ISN impedance stabilization networks are used in EMC testing to measure conducted common-mode noise on telecom cables for ITE, meeting CISPR 22/32 requirements. The ISN provides a stable common-mode termination impedance during tests
