怎么在DSO9254A中保存两个具有相移的波形

只要从同一触发器捕获两个波形，就会保留相位。
要自己测量相位，您必须编写一个程序来读取两个波形，并计算相位。
你为什么不用范围来衡量阶段？

     以下为原文

  As long as the two waveforms were captured from the same trigger, the phase will be preserved. To measure the phase yourself, you will have to write a program to read the two waveforms, and calculate the phase.

Why don't you just use the scope to measure the phase?

我只需要原始sata进行进一步分析。
我可以通过两种方式保存数据：1：暂停测量 - >“屏幕数据”选项 - >将数据保存到两个文件中2：运行测量 - >“屏幕数据”选项 - >将数据保存为两个
文件这两种方式的相移是否相同？

  I just need the raw sata for further analysis. I can save the data in two ways:

1: pause the measurement -> „On-screen Data“ option -> save data into two files
2: run the measurement -> „On-screen Data“ option -> save data into two files

Are the phase shifts in these two ways the same?

您是要保存示波器所做的测量，还是保存文件，以便进行测量？
它们是非常不同的东西。

  Do you want to save the measurement that the scope makes, or save the files, so that you can do the measurement? They are very different things.

我想将测量的波形保存到文件中。
关键问题是在保存与否之前停止测量是否有所不同。

  I want to save the measured waveforms into files. The key question is if it makes difference to stop the measurement before saving or not.

另外，我不认为将数据捕获为进行测量。
测量相位或峰峰值电压更像是我认为的测量方法。
作为一种形式，您应该在保存数据之前始终停止范围。
如果作用域正在运行，它将停止，保存数据（之前指定的所有通道），然后继续。
停止允许您查看屏幕上的数据，并确定它是否是好数据，或者是否某种异常导致捕获到不良数据。
它还允许您检查是否已告知范围以保存两个通道，并且文件名是正确的。

  As an aside, I don't think of capturing data as making a measurement. Measuring phase, or peak-to-peak voltage, is more what I think of as making a measurement.

As a matter of form, you should always stop the scope before you save the data. If the scope is running, it will stop, save the data (all of the channels previously specified), then continue. Stopping allows you to look at the data onscreen, and make a decision as to whether it's good data, or if some sort of anomaly caused bad data to be captured. It also allows you to check that you have told the scope to save both channels, and that the filename is correct.
