有什么方法来同步两个电源？

嗨，我了。
现在两个瞬态是同步的，但是相移仍然在变化。
有人可以帮我解决这个问题吗？
非常感谢。
马丁

  Hi, me again.
Now the two transients are synchron, but the phaseshift is still changing.
Can anybody help me please with this problem?

Thanks a lot.
Martin

嗨Martin，控制交流电源时序的振荡器有一个固有的不准确性。
您所看到的是这种不准确性在一段时间后会出现并且波形不同步。
你能否为我回答几个问题：1。你是否从连接到另一个触发器的触发器中取出了触发器？
2.您能提供用于生成脉冲的仪器命令序列吗？
我不能对此解决方案作出任何承诺，因为我从未做过，但我确实有一个想要探索的想法。
马特

  Hi Martin,

The oscillator that controls the timing in the AC Source has an inherent inaccuracy to it.  What you are seeing is this inaccuracy build up after a while and the waveforms are getting out of sync.  Can you answer a few questions for me:

1.  Do you have the trigger out from one connected to the trigger in of the other?
2.  Can you provide the sequence of instrument commands that you use to generate your pulses?

I can't make any promises on a solution for this as I have never done it but I do have an idea that I would like to explore.

Matt

嗨，马特，你的问题：+1。
你是否有一个连接到另一个触发器的触发器？+ - 是。
因为我写了“大师”和“奴隶”+2。
您能提供用于生成脉冲的仪器命令序列吗？+ - 确定。
我非常高兴你的帮助，希望你的想法;-)“instr”是我的主电源;
“instr2”我的奴隶（只是一个同义词）// ######################################

  Hi Matt,
to your questions:

+1. Do you have the trigger out from one connected to the trigger in of the other?+
- Yes. Because of that i wrote "Master" and "Slave"

+2. Can you provide the sequence of instrument commands that you use to generate your pulses?+
- sure. I´m very happy about your help and hopefully for your idea ;-)

"instr" is my Master Power-Supply; "instr2" my Slave (just a synonym)

greets,

你的程序看起来不错。
问题在于瞬态系统不是100％准确，并且两个交流电源之间不一样。
在每个周期之后，波形失去一点相位同步。
我们需要找到一种在每个波形后重新同步的方法，并将触发器发送到从属单元。
一种想法是将从属单元设置为“LIST：STEP ONCE”并从主单元运行它的触发器。
您需要添加一些虚拟步骤以保持正确的时间，但这可能会起作用。
一个问题：你有两个AC SOurces的输出连接在一起还是它们挂钩到不同的东西？



     以下为原文

  Your program looks good.  The issue is that that transient system is not 100% accurate and is not the same between the two AC Sources.  After every cycle the waveform loses a bit of the phase synchronization.  We need to find a way to resync after each waveform and to send a trigger out to the slave unit.    

One idea would be to set the slave unit to "LIST:STEP ONCE" and run it off triggers from the master unit.  You would need to add in some dummy steps in order to keep the timing right but this might work.  

One question: do you have the outputs of the two AC SOurces hooked together or are they hooked to different things?
