5 TEST DATA 5.1 Antenna Port Conducted Emissions The direct measurement of emissions at the antenna port of the EUT is achieved by use of a RF connection to a spectrum analyzer or power meter. Description of Measurement The cable and attenuator factors are loaded into the analyzer or power meter allowing for direct measurement readings without the need for further corrections. Measurement (dBm) + Cable factor (dB) + External Attenuator (dB) = Corrected Example Reading (dBm) Calculations Margin (dB) = Limit (dBm) – Corrected Reading (dBm) Block Diagram Spectrum Ext.
