N6700编程帮助

嗨Rob，让我们看看我可以在这里提出什么建议：1。我认为最好的办法是监控运行状态寄存器。
我在这里写了一篇关于这个功能的博客文章：电源注册博客文章。
您想要监视交泛位。
2.您需要使用数字化仪功能。
您可以将其设置为与瞬态触发器同步。
我在这里写了一篇博文：Sync Transient和Measurement Triggers博文。
请注意，如果您更容易解析，则可以将测量值读回ACSII而不是二进制格式。
如果您需要任何其他信息，请告诉我。

  Hi Rob,

Let's see what suggestions I can make here:

1.  I think that the best thing would be to monitor the operating condition register.  I wrote a blog post about this feature here: Power Supply Registers Blog Post.  You want to monitor the trans-active bit.  

2.  You need to use the digitizer feature.  You can set it up to sync it with your transient trigger.  I wrote a blog post about that here: Sync Transient and Measurement Triggers Blog post.  Please note that you can read your measurements back as ACSII rather than binary format if that is easier for you to parse.  

Let me know if you need any other information.

你好马特，谢谢你的回复。
我已经设法通过阅读示例和大量的反复试验来完成这些编程。
它现在通常工作正常。
由于默认超时，我使用* WAI命令是有问题的;
增加超时解决了我到达那里的错误。
剩下的问题是试图从N6752A模块中获​​取电压和电流数据：我可以得到一个，或者另一个，但不能同时得到两个。
我的理解是这是模块的限制。
检索电压或电流的“FETCH：ARRAY”步骤工作得很好，并使用相应的“SENSE：SWEEP”命令使用时间间隔和我指定的点数将数据返回到Excel。
我在2012年回顾了关于N6700B上ELOG命令的帖子，并认为这些可能有助于我解决获得电压和电流的问题，但Command Expert中似乎完全没有这些命令。
你期望他们在那里吗？
谢谢，罗布

  Hello Matt,

Thanks for the reply.

I've managed to get this programming mostly done by reading examples and a lot of trial-and-error. It’s generally working fine now. My use of the *WAI command was problematic because of the default timeout; increasing the timeout solved the error I was getting there.

The remaining issue is trying to get both voltage and current data back from the N6752A modules: I can get one, or the other, but not both. My understanding is that this is a limitation of the modules. The “FETCH:ARRAY” step to retrieve either the voltage or current works just great, and the data is returned to Excel using the time interval and number of points I’ve specified using the appropriate “SENSE:SWEEP” commands.

I read your post from back in 2012 about the ELOG commands on the N6700B and thought perhaps those might help me solve the problem of getting both voltage and current, but these commands appear to be entirely absent from Command Expert. Would you expect them to be there?

Thanks,
Rob

嗨Rob，N6752A内置一个数字转换器，可以测量电压或电流，但不能同时测量。
N676xA模块有2个数字转换器，可以同时测量两个数字转换器。
ELOG是一个非常复杂的功能，需要循环在缓冲区填充之前回读数据，所以我不认为你可以编写一个能够充分利用该功能的命令专家程序。
我们确实有一些我在VB中编写的ELOG示例，我们应尽快发布。

  Hi Rob,

The N6752A has a single digitizer in it that can measure either voltage or current but not both simultaneously.  The N676xA modules have 2 digitizers that allow you to measure both at the same time.  

ELOG is a pretty complicated feature that requires a loop to read back the data before the buffer fills so I do not think that you can write a command expert program that will fully utilize the feature.  We do have some ELOG examples that I wrote in VB that we should be posting soon though.

再次感谢，马特。
我们有几个N6761A模块，并计划转移到这个应用程序之一。
很高兴知道如果我们想要在N6752A模块上启用该功能，我们可以转向VB - 我期待看到编程示例。编辑：RobR于2015年11月19日下午5:25

  Thanks again, Matt.

We have a couple of N6761A modules and plan to move to one of those for this application. It's good to know that we could move to VB if we want to enable the capability on the N6752A modules -- I'll look forward to seeing programming examples.
