远程捕获自动电压测量

我不确定你到底想要什么。
在捕获中，通道1“仅上升”一次吗？
您是否在通道1超过某个阈值的确切时刻寻找通道2上单个捕获点的电压值？
这需要一点思考和编程。
由于上升时间是有限的，非零，也许你正在寻找通道2在通道1上升的某个短时间内的平均电压？
如果通道1在捕获期间仅上升一次，则相对容易...在通道1上触发，在通道2上设置“水平门”，然后在门功能的输出上进行电压测量。

Keysight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。

  I'm not sure exactly what you want here.

Does Channel 1 "rise" only once in a capture?

Are you looking for the voltage value of single captured point on Channel 2 at the exact instant that Channel 1 crosses some threshold value? This requires a little thought and programming.

Since the rise time is finite, and non-zero, maybe you're looking for the average voltage on Channel 2 during some short time period during which Channel 1 is rising? If Channel 1 only rises once during a capture this is relatively easy... Trigger on Channel 1, set up a 'Horizontal Gate' on Channel 2, then put a voltage measurement on the output of the gate function.

通道1在捕获中仅上升一次。
理想情况下，是的，当通道1超过阈值时，我正在寻找通道2上的单个电压值。
现在考虑到这可能很困难，我认为如果窗口相对较小，我可以使用通道2的平均值。
我将尝试使用水平门，看看这是否足以满足我的目的。
谢谢你的回复。

  Channel 1 will rise only once in a capture.

Ideally, yes, I am looking for the single voltage value on channel 2 when channel 1 passes a threshold.

Now given this may be difficult, I think I could live with an average value of channel 2 if the window is relatively small.  I will experiment with the Horizontal Gate to see if this will be accurate enough for my purposes.

Thanks for the response.

门窗可以任意小。
您应该记住存在一些示波器噪声，并且您可能希望限制测量的BW，因此10到20个样本宽的门可能是正确的。

  The gate window can be arbitrarily small.

You should remember that there is some scope noise, and that you probably want to limit the BW of your measurement, so a gate that's 10 to 20 samples wide is probably about right.
