B4621A，默认conf 16962 DDR3 x16 32bit？

您使用的是最新版本的LA SW吗？
你使用DDR设置助手吗？
如果您使用它并正确回答问题，它应该找到正确的配置文件。
如果您没有，那么您还没有加载所有必要的工具？

  Are you using the most recent version of the LA SW?

Did you use the DDR Setup Assistant?

If you use that, and answer the questions correctly, it should find the correct configuration file.

If you don't have that available, then you haven't loaded all of the necessary tools?

当然，安装了所有最新的SW组件，你可以参考附图，看看16962 DDR3 x16 32bit配置文件丢失...

  Sure, all the latest SW components installed, you can reference to the picture attached
and see 16962 DDR3 x16 32bit config file missing...

好的，我查了一下。
没有32位x16配置，因为这不是由Keysight或Futureplus销售的任何硬件直接支持的标准设置。
您必须修改现有的16位配置，添加额外的16位。
你从来没有真正回答我的问题，所以上面的答案并不是确定的。
你在运行什么版本的LA SW？
你使用DDR设置助手吗？
您是否已从Keysight网站加载所有DDR工具？

     以下为原文

  OK, I checked. There is no 32bit x16 configuration, because that is not a standard setup which is directly supported by any of the HW sold by Keysight, or Futureplus. You will have to modify an existing 16bit configuration, adding the additional 16 bits.

You never really answered my questions, so the above answer is not definitive.

What version of LA SW are you running?

Did you use the DDR Setup assistant?

Have you loaded all of the DDR Tools from the Keysight website?

我的sw / hw配置如下：LA SW v5.90,16902B Win7 x64，B4621解码器v5.90,16962 x 2，E5845A，DDR3 x16 32bit（



     以下为原文

  my sw/hw config is as follows:
LA SW v5.90, 16902B Win7 x64,
B4621 decoder v5.90, 
16962 x 2, E5845A, DDR3 x16 32bit ( < 1867Mb/s).

That is really strange why DDR2 x16 32bit is a standard config available for 16962 boards,
and DDR3 x16 32bit is not... why so ?

没有标准方案可将2 x16 DDR3芯片连接到x32配置的分析仪。
我已经看过它，使用2个插入器或SoftTouch适配器。
可能还有其他方案可行。
因为没有标准方案，所以没有标准配置文件。
根据您告诉我的内容，您可能在每个2 DDR3芯片上都有一个内插器（W3631A或W3636A）。
在16位配置中，此插入器将地址，命令和数据总线带到2个分析器卡。
如果您按照标准连接，地址和命令转到一个卡，16位数据从Pod A转到第二个卡。由于双采样模式，数据总线使用32个通道。
这使得第二张卡上有32个频道可用。
您可以通过将第二个E5845A的Pod A连接到第二个卡的Pod 3来扩展此配置。
然后，您可以将Pod 1和2的通道映射复制到pod 3和4.一旦完成，您可以保存该配置并使用它来完成测量任务。
您可能必须调整EyeScan的“读取”和“写入”选项卡上的信号分组，但同样可以将其保存到配置文件中以备将来使用。

     以下为原文

  There is no standard scheme for connecting 2 x16 DDR3 chips to an analyzer in a x32 configuration. I have seen it done, using 2 interposers, or SoftTouch adapters. There may be other schemes which will work, as well. Because there's no standard scheme, there's no standard configuration file.

Based on what you have told me, you may have an interposer (either W3631A or W3636A) on each of your 2 DDR3 chips. In a 16 bit configuration this interposer brings the Address, Command, and Data buses to the 2 analyzer cards. If you follow the standard connection, Address and Command go to one card, and the 16 bits of Data goes to the second card, from Pod A. The Data bus uses 32 channels, due to dual-sample mode.

This leaves 32 channels available on the second card. You could extend this configuration by connecting Pod A of the second E5845A to Pod 3 of the second card. Then you could duplicate the channel mapping of Pods 1 and 2 into pods 3 and 4. Once that's done, you could save that configuration and use it to accomplish your measurement task.

You might have to adjust the signal groupings on the Read and Write tabs of EyeScan, but, again, that could be saved into the configuration file for future use.
