EE主要进行固件开发的最佳范围选择

问答对人有帮助，内容完整，我也想知道答案 0 嗨，我希望购买带有I2C / SPI / RS232 / UART选项的DSO4104，或带有免费500Mpts和一个免费选项的DSO9104（这将是I2C / SPI / RS232 / UART捆绑选项）。我打算按如下方式使用它： - 调出原型硬件，最高可达100MHz数字信号。 - 调试CPU之间的串行总线通信。 - 将调试数据从CPU发送到示波器，以获得对嵌入式软件操作的可视性。我正在处理的大多数CPU或带有嵌入式CPU核心的ASIC没有任何软件调试工具支持（没有JTAG等）。但是通常有一个免费的串行总线可以用作调试输出端口。 9000附带的深存将对最后一项非常有用。此外，9000上的串行协议解码支持似乎更强大，并提供更多功能。但就波形更新率而言，4000x似乎遥遥领先。如果没有9000的更新速率会有多大问题？此外，4000x还带有区域触发标准。我已经考虑过我需要多少区域触发器，而且对于我的用例来说，我似乎不会使用它。价格方面，两者都很昂贵，但这些（约5000美元）之间没有太大差异，所以如果我做出暴跌，我不想后悔我的决定。你会推荐什么？以上来自于谷歌翻译以下为原文 Hi, I am looking to either buy the DSO4104 with the I2C/SPI/RS232/UART options, or the DSO9104, which comes with free 500Mpts and one free option (which will be the I2C/SPI/RS232/UART bundle option). I am intending to use it as follows: - To bring up a prototype hardware, with up to 100MHz digital signals present. - To debug serial bus communication between CPU's. - To send debugging data from a CPU to the scope to gain visibility to the operation of the embedded software. Most CPU's or ASIC's with embedded CPU cores hat I am dealing with don't have any software debugging tool support (no JTAG etc). But there is usually one free serial bus that I can use as a debugging output port. The deep memory that comes with the 9000 will be very useful for the last item. Also, the serial protocol decoding support on the 9000 seems to be more powerful and offers more functionality. But the 4000x seems to be far ahead in terms of waveform update rate. How much of a problem will it be to not have this update rate with the 9000? Also the 4000x comes with the zone trigger standard. I have thought about how much I will need the zone trigger, and it seems for my use cases, I won't use it much. Price wise, both are expensive, but there isn't much difference between these (around $5000), so if I make the plunge, I don't want to regret my decision later. What would you recommend? 0

答案对人有帮助，有参考价值 0 根据你所说的，9000系列似乎是一个更好的选择。对于串行总线工作，快速更新速率不太重要，更灵活的串行触发和解码将更有用。我建议您查看9000的MSO选项。数字输入可以与串行触发功能一起使用，释放模拟通道以查看信号质量。免责声明：为了获得更可靠的响应，您应该考虑致电当地的安捷伦技术呼叫中心。安捷伦论坛在“可用”的基础上进行监控，并不一定是解决技术问题的最快方式。以上来自于谷歌翻译以下为原文 Based on what you've said, the 9000 family seems like a better choice. For Serial bus work, fast update rate is less important, and more flexible serial triggering and decode will be more useful. I'd recommend that you look at the MSO option for the 9000. The digital inputs can be used with the serial trigger capability, freeing up the analog channels for looking at signal quality.
