JH5500A  Digital TV Signal Generator

JH5500A  digital TV signal generator adopts embedded system. It can run more stably and provide a more convenient operation. This equipment supports US standards of ATSC(8VSB & QAM-B)，EU standards of DVB-T/H、DVB-T2 and DVB-C, Japanese standards of ISDB-T, Chinese standards of DTMB(DMB-TH,ADTB-T).This is a 19＂ 2U standard unit . It can play TS code stream which can be digitally modulated and up-converted to the frequency of 47～862MHz and 950～2150MHz 

JH5500A  Digital TV Signal Generator

       JH5500A为一台多制式DTV（数字电视）信号发生器，本机一台即可应对日本、中国、美国、欧州、巴西等世界各国的数字电视（包括地面、有线、卫星），使用方式为选择其中一个制式加以输出_。

功能特点：

• 设备本身具有TS流文件播放功能，集码流发生器和调制器于一体，无需外加TS流信号源
• 输出频率从47～3000MHz，*覆盖VHF、UHF电视频道
• RF输出电平连续可变，可变范围（QAM）-31.5 ～ 0dBm、（OFDM）-34.5 ～ -3dBm，（增加电频输出选件可达到-11dbm）此功能可以很好的测试接收机的灵敏度
• 支持制式有

地面：DVB-T/T2，ATSC，ISDB-T,DTMB

有线：DVB-C/C2，J.83B
