Before you begin testing with the CDNs you will need to establish calibrated drive levels corresponding to your desired test levels. During drive level calibration, the RF signal level being injected to the Coupling Decoupling Network is adjusted incrementally until the voltage level measured at the 150Ω to 50Ω adapter (ADA-515-2) connected to the EUT port of the CDN is approximately equal to the Umr value given in the table below. The ADA-515-2 and accessories needed for this test are available via Shieldingshop as well.
