The Model CDN10K-AF Series are coupling/decoupling networks to couple common mode signals onto unscreened un-balanced wires. Models exist for two and four cables. The networks are designed to meet the NAMUR NE21 standard requirements. The Coupling Port Power Level rating on these units will accommodate the higher RF power required to achieve the desired test level. This higher power is necessary to compensate for the basic insertion loss from the RF Disturbance port to the EUT port, the test standard modulation requirements, as well as reflections that may occur in the CDN circuits. Calibration adapter sets (set of two adapters for AE and EUT ports) are required for calibration of these networks. 150-50 ohm adapter set (CR00100CD, set of 2) is available for these networks.
