ADI有没有12位的DAC 和DAC转换IC带内部基准的，8PIN管脚封装的，单通道的。速度不用太快 的，1MS之内 就行了。我想替换 ADS7834 ,DAC7611不知道有没有推荐啊？ADI的大神们

嗨，M8190A上的安捷伦大师，我只买了2个M8910A（产品版本2）来取代原版1单元。我试图从M8190A生成多个音调信号。但是我总是通过freq在我想要的信号周围得到不需要的多个信号产物。偏移20.8KHz（312,000个样本长度），或2.08KHz，3,120,000个样本长度。即使我将所有“1”加载到通道1并且将“0”加载到通道2，我仍然遇到同样的问题。有时它没有出现，信号很干净。但大部分时间都发生在我的两个单位上。我的版本1单元没有出现此问题。我已经想到并检查了ref信号，从内部采样信号（从“采样时钟输出”端口始终有+ / 1 270Hz信号）并重启PC和M8190A（和驱动程序）多次，但是甚至找不到解决方法！很沮丧!!仅供参考，我使用C＃生成DAC值并使用IVI驱动程序加载到设备。但就像我说的，即使加载“1”和“0”也会导致同样的问题。我几乎得出的结论是硬件有问题。您的及时帮助真的很感激!!!射线 以上来自于谷歌翻译 以下为原文Hi, Agilent guru on M8190A, I just got 2 of M8910As (product version 2) to replace original version 1 unit. I was trying to generate multiple tone signals from M8190As. But I always got unwanted multiple products of signals around my desired signals with freq. offset 20.8KHz (for 312,000 sample length), or 2.08KHz for 3,120,000 sample length.Even if I loaded all "1" to channel 1 and "0" to channel 2, I still got the same problem. Sometimes it didn't show up and the signals were very clean. But most of time it happened, on both of my units. I didn't get this problem with my version 1 unit. I have thought of and checked ref signal, sampling signals from internal (which always has +/1 270Hz signals around from "Sample Clock out" port) and rebooted PC and M8190A (and driver) many times, but couldn't find even a workaround!!Very frustrated!! FYI, I am using C# to generate the DAC values and load to the unit with IVI driver.But like I said, even loading "1" and "0" will cause the same problem. I am almost coming to the conclusion that the hardware has the problem. Your timely help is truly appreciated!!! Ray
