详细介绍
DX 7500 系列航空基地电台，结构紧凑，外形美观且结实耐用的DSP（数字集信号处理器），它既符合美国25 kHz 频间要求，也同时符合国际上最新的8.33 kHz 频间要求。
该系列的产品可以这样进行配置：把电台当作本地控制的单元，与桌面上的麦克和内话系统进行连接使用。这种配置下会使它的功能和操控性达到最佳效果。尤其是7010型便携式电台，除是输出功率不一样以外，它的输出功率有10瓦、100瓦或200瓦几种。DX 7500 系列电台还可以配置成一台本地控制单元与E & M界面或“远程声音控制”系统连接使用。除此之外，7500的另一个特点是前后都有耳机接口，方便使用。注意：一些早期的7500系列电台没有“侧音”功能，如果用户需要这一功能，可能要提前跟厂家说明。
DX 7500 系列航空基地电台适用于多种电源，AC或DC电源接口，或者选配远程接口。产品的标配是AC电源，配上单“N”型天线接口。 For applications in RF dense environments, the 7500 can be configured with (optional separate) RX/TX antenna ports, or with a common Antenna I/O and RX filter “IN” and “OUT” connections. These configurations are for installations requiring RF combining and external RX filtering respectively. Series Aeronautical Base Stations are rugged, state-of-the-art DSP (Digital Signal Processor) based units which are designed to meet the existing (US) 25 kHz channel requirements and the new 8.33 kHz international requirements. These versatile products can be configured as a (direct) locally controlled unit with (desk) microphone and internal speaker; in this configuration all functions and operation are identical to those of the 7010 mobile unit, except the power output, which may be 10, 100 or 200 Watts (PEP). The DX 7500 Series Aeronautical Base Station can also be configured as a locally controlled unit with E & M interface or “Tone Remote”. In addition to the functions described above, the 7500 also features front and rear jacks for use with an aeronautical headset. Note: Some earlier versions of the basic 7500 do not feature “side-tone”. If side-tone is required, this option should be installed at the factory.
DX Radio’s 7500 Series Aeronautical Base Stations can be supplied with a variety of RF power levels, AC or DC power requirements and remote interface options. The standard unit is an AC operated unit with a single type “N” antenna connector. For applications in RF dense environments, the 7500 can be configured with (optional separate) RX/TX antenna ports, or with a common Antenna I/O and RX filter “IN” and “OUT” connections. These configurations are for installations requiring RF combining and external RX filtering respectively.
