ETSI EN 300 390涵盖了专用移动无线电（PMR）服务电台中使用的无线电发射机和接收机的技术要求。它适用于在地面移动服务中使用，在30 MHz和1 GHz之间的无线电频率上运行，信道间隔为12,5 kHz、20 kHz和25 kHz，用于数据或语音和数据。表1:无线电通信服务频带无线电通信服务频带宽度为30 MHz至1000 MHz接收30 MHz至1000 MHzIt适用于连续和/或不连续传输的设备。 该设备包括发射机及相关编码器和调制器和/或接收机及相关解调器和解码器。本文件还适用于使用集成天线并用于传输数据和/或语音的模拟和数字组合无线电设备。本文件是对ETSI EN 300 113[i.5]的补充，ETSI EN 300 113[i.5]涵盖了带有内部或外部射频连接器的无线电设备。在以下情况下:组合全带宽模拟/全带宽数字设备，如果设备的模拟部分已根据ETSI EN 300 296[6]进行测量； 已根据本文件进行测量，并使用附加装置重新测量的设备，使用另一种调制方式，且不影响设备的任何其他特性；只有本文件的部分要求适用。这些要求见第4.8条。

ETSI EN 300 390 covers the technical requirements for radio transmitters and receivers used in stations in the Private Mobile Radio (PMR) service.It applies to use in the land mobile service, operating on radio frequencies between 30 MHz and 1 GHz, with channel separations of 12,5 kHz, 20 kHz and 25 kHz, intended for data or speech and data.Table 1: Radiocommunications service frequency bandsRadiocommunications service frequency bandsTransmit30 MHz to 1 000 MHzReceive30 MHz to 1 000 MHzIt applies to equipment for continuous and/or discontinuous transmission.The equipment comprises a transmitter and associated encoder and modulator and/or a receiver and associated demodulator and decoder.The present document also applies to combined analogue and digital radio equipment using an integral antenna and intended for the transmission of data and/or speech.The present document is complementary to ETSI EN 300 113 [i.5], which covers radio equipment with an internal or external RF connector.In the cases of:combined full bandwidth analogue/full bandwidth digital equipment, if the analogue part of the equipment has already been measured according to ETSI EN 300 296 [6];equipment which has already been measured according to the present document, and is remeasured with an add-on device, using another type of modulation without affecting any other characteristics of the equipment;only some of the requirements of the present document apply. These requirements are given in clause 4.8.
