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(tái)多制式DTV（數(shù)字電視）信號(hào)發(fā)生器，本機(jī)一臺(tái)即可應(yīng)對(duì)日本、中國、美國、歐州、巴西等世界各國的數(shù)字電視（包括地面、有線、衛(wèi)星），使用方式為選擇其中一個(gè)制式加以輸出。
功能特點(diǎn)：
- 設(shè)備本身具有TS流文件播放功能，集碼流發(fā)生器和調(diào)制器于一體，無需外加TS流信號(hào)源
- 輸出頻率從47～3000MHz，*覆蓋VHF、UHF電視頻道
- RF輸出電平連續(xù)可變，可變范圍（QAM）-31.5 ～ 0dBm、（OFDM）-34.5 ～ -3dBm，（增加電頻輸出選件可達(dá)到-11dbm）此功能可以很好的測(cè)試接收機(jī)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(wèi)星：DVB-S/S2，ISDB-S
- 一體化設(shè)計(jì)，外接鼠標(biāo)鍵盤顯示器即可設(shè)置參數(shù)，操作更方便
主要應(yīng)用：
- 數(shù)字電視標(biāo)準(zhǔn)信號(hào)發(fā)生器
- 機(jī)頂盒與一體機(jī)研發(fā)，性能檢測(cè)及生產(chǎn)測(cè)試用信號(hào)源
- 廣播電視傳輸系統(tǒng)模擬，演示、展會(huì)、電器賣場(chǎng)等
- DTV 芯片開發(fā)(調(diào)諧器/解碼)
