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為一臺多制式DTV（數字電視）信號發生器，本機一臺即可應對日本、中國、美國、歐州、巴西等世界各國的數字電視（包括地面、有線、衛星），使用方式為選擇其中一個制式加以輸出_。

功能特點：

• 設備本身具有TS流文件播放功能，集碼流發生器和調制器于一體，無需外加TS流信號源
• 輸出頻率從47～3000MHz，*覆蓋VHF、UHF電視頻道
• RF輸出電平連續可變，可變范圍（QAM）-31.5 ～ 0dBm、（OFDM）-34.5 ～ -3dBm，（增加電頻輸出選件可達到-11dbm）此功能可以很好的測試接收機的靈敏度
• 支持制式有

地面：DVB-T/T2，ATSC，ISDB-T,DTMB

有線：DVB-C/C2，J.83B

衛星：DVB-S/S2，ISDB-S

• 一體化設計，外接鼠標鍵盤顯示器即可設置參數，操作更方便

主要應用：

• 數字電視標準信號發生器
• 機頂盒與一體機研發，性能檢測及生產測試用信號源
• 廣播電視傳輸系統模擬，演示、展會、電器賣場等
• DTV 芯片開發(調諧器/解碼)
