GBR信号,很少这么标的,分量视频信号,一般标识Y/Pb/Pr或者Y/Cb/Cr,用三色的RCA莲花头线连接。也有和VGA的15针D-sub接口共用的,线的一头是VGA接口,另一头是3色莲花头接口。

用AltiumDesigner软件打开。步骤如下:
1、首先打开AltiumDesigner软件,新建一个cam文件,依次点击左上方的功能菜单“file”>“new”>“camdocument”;
/iknow-piccdnbceboscom/77094b36acaf2eddfe567032831001e938019341"target="_blank"title="大图"class="ikqb_img_alink">/iknow-piccdnbceboscom/77094b36acaf2eddfe567032831001e938019341x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-piccdnbceboscom/77094b36acaf2eddfe567032831001e938019341"/>
2、然后导入gbr格式文件,依次点击“file”>“import”>“gerber”;
/iknow-piccdnbceboscom/3b87e950352ac65c57c258a8f5f2b21192138a21"target="_blank"title="大图"class="ikqb_img_alink">/iknow-piccdnbceboscom/3b87e950352ac65c57c258a8f5f2b21192138a21x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-piccdnbceboscom/3b87e950352ac65c57c258a8f5f2b21192138a21"/>
3、在打开的窗口中选择需要打开的gbr文件;
/iknow-piccdnbceboscom/cefc1e178a82b901a318fae87d8da9773812efb0"target="_blank"title="大图"class="ikqb_img_alink">/iknow-piccdnbceboscom/cefc1e178a82b901a318fae87d8da9773812efb0x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-piccdnbceboscom/cefc1e178a82b901a318fae87d8da9773812efb0"/>
4、然后点击“OK”;
/iknow-piccdnbceboscom/9922720e0cf3d7ca5c5006adfc1fbe096a63a942"target="_blank"title="大图"class="ikqb_img_alink">/iknow-piccdnbceboscom/9922720e0cf3d7ca5c5006adfc1fbe096a63a942x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-piccdnbceboscom/9922720e0cf3d7ca5c5006adfc1fbe096a63a942"/>
5、然后gbr文件内容就在AltiumDesigner软件中显示出来了。
/iknow-piccdnbceboscom/71cf3bc79f3df8dc792fb64ac311728b461028de"target="_blank"title="大图"class="ikqb_img_alink">/iknow-piccdnbceboscom/71cf3bc79f3df8dc792fb64ac311728b461028dex-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-piccdnbceboscom/71cf3bc79f3df8dc792fb64ac311728b461028de"/>
GBR指的是保证比特率类型的业务(Guaranteed Bit Rate),实际上就是实时业务,如流媒体这种要求要保证一定速率的业务。LTE你应该知道吧,呵呵,长期演进么(long term evolution)
