ETSI EN 303 372-1适用于ODU，用于接收来自地球静止卫星的频率范围内的卫星广播 频带10.7GHz至12.75GHz。ODU从卫星接收电磁波。它会放大接收信号 在低噪声下，将其转换为较低的频带，并使其可用于接口上的IDU。部分IDU功能可与ODU集成。在这种情况下，本文件仅适用于 传统的ODU功能。本文件包含证明无线电设备有效使用和支持 有效利用无线电频谱以避免有害干扰。

ETSI EN 303 372-1 applies to ODUs for satellite broadcast reception from geostationary satellites in the frequency band 10,7 GHz to 12,75 GHz. An ODU receives electromagnetic waves from a satellite. It amplifies the receive signal at low noise, converts it to a lower frequency band and makes it available to the IDU on an interface.Part of the IDU functionality may be integrated with the ODU. In that case the present document applies only to the conventional ODU functionality.The present document contains requirements to demonstrate that radio equipment both effectively uses and supports the efficient use of radio spectrum in order to avoid harmful interference.
