ISN/CDN-C Series — coaxial Coupling Decoupling Networks / Impedance Stabilization Networks — Com-Power dual-function units for 50 Ω and 75 Ω coax. Use as ISN for conducted emissions (150 kHz–30 MHz) or as CDN for IEC 61000-4-6 conducted immunity (150 kHz–230 MHz).
Choose Model by characteristic impedance — C50E (50 Ω) or C75E (75 Ω) BNC EUT/AE ports.
150 Ω common-mode termination per CISPR 22/32 — stable, repeatable disturbance voltage at the measurement port.
Individually calibrated; unpainted bottom bonds to reference ground plane — three-year warranty; pairs with SPA-900TG series spectrum analyzer / EMI receiver.
