更好的避免干扰？ 另外，AD8120的固定增益为2，那么输出VGA信号需要再衰减1/2才可以么？ 谢谢

现有计算机显卡输出VGA线较长（3米），为了改善信号质量，想设计单片8120线路（无8122），通过电位器调节达到预期效果，可否？一般AD810只能配合8122使用么？VGA的地怎么处理能更好的避免干扰？另外，AD8120的固定增益为2，那么输出VGA信号需要再衰

通过UTP电缆传输的信号会容易受哪些影响？ 会发生哪些常见变化？

我找不到一个发布这个的好地方，但是我有一个安捷伦测试机架，里面装有安捷伦电源和其他东西，后面的所有电缆都很乱。我想清理它，让它看起来更专业。我认为电源的电源线会夹在前后柱上，但似乎没有任何夹子。有没有人有清理那只老鼠的下一根电缆的技巧？您是否将电缆保持在门和柱之间或设备侧面？您是否建议购买“正确”长度的新电源线并摆脱设备附带的长电源线？等等！ 以上来自于谷歌翻译 以下为原文I couldn't find a good place to post this, but I have an Agilent test rack with Agilent power supplies and other things stacked up inside and all of the cabling in the back is a mess.I want to clean this up and make it look more professional.I would think that the power cables from the power supplies would clip into the front and rear columns, but there don't seem to be any clips.Does anyone have tricks for cleaning up that rat's next of cables?Do you keep your cables between the door and the column or to the side of the equipment?Do you recommend buying new power cords that are the 'right' length and getting rid of the long ones that came with the equipment? etc. Thanks!

我使用PIC32 MX795F512L进行SPI通信。在调试模式下，SPI1CON显示值0xC120，但我正在发送0x8120。我不知道为什么会发生这样的事？波特率值设置正确，但是当我将“A”写入

我有一个86720A频率扩展单元。我有一个工作的8672A合成器，并希望将两者结合在一起形成一个20 MHz到18 ghz的合成器。然而，我一直在寻找一本手册或原理图来向我展示如何将两者结合在一起。有一个圆形的多芯电缆将两个单元的背面连接在一起，但我没有电缆或如何制作一个电路板（即引脚输出）。此外，也可能在背面制作一些同轴射频连接。是否有人有这些，或86720A的手册，显示他们如何连接？谢谢，富 以上来自于谷歌翻译 以下为原文I have an 86720A frequency extension unit.I have a working 8672A synthesizer, and would like to marry the two together to form a 20 MHz to 18 ghz synthesizer.Yet, I have been looking for a manual or schematic to show me how to hook the two together.There is a round multipin cable to connect the backsides of the two units together, but I do not have the cable or a schematic on how to make one up (i.e. the pin outs).Also, there are probably some coaxial rf connections to be made on the backside also.Does anyone have one of these, or the manual for the 86720A that shows how they connect up?Thanks, Rich
