示波器探头最大瞬态电压是否可以在信号中使用

不要这样做。
除了安全问题，还有可能破坏范围的输入。
作为10：1探头，300V RMS作为30V RMS提供给示波器。
示波器的前端可以处理该电压，并消耗产生的功率。
探头可以处理> 400V的瞬态电压。
达到600V RMS意味着耗散4倍的功率，前端电路可能无法处理60V RMS。

  Don't do it.

Besides the safety issues, there's the possibility of destroying the input of the scope. As a 10:1 Probe, 300V RMS is presented to the scope as 30V RMS. The front end of the scope can handle that voltage, and dissipate the power generated. The probe can handle transients to >400V. Going to 600V RMS means dissipating 4 times as much power, and the front end circuits may not be able to handle the 60V RMS.

感谢范围可以处理1000x是安捷伦DSO1002A我应该更好地使用差分探头吗？
我有一个额定电压高达700 V.电缆额定电压为1000V。



     以下为原文

  Thanks the scope can handle 1000x is the Agielnt DSO1002A should I better use differential probe for that? I have one rated up to 700 V. Cables rated at 1000V.

您的信号是差分信号，还是一侧接地？
如果它是差分的，那么你应该使用差分探头。
根据数据表，您可以选择探头： - 10076B - 250 MHz，100：1,4 kV无源探头 - N2771B - 50 MHz，1000：1 30 kV无源探头 - N2791A - 25 MHz，700V差分探头 - N2891A
- 70 MHz，7 kV差分探头什么是瞬态的BW？
您可以通过使用.5 /上升时间来估计。
一旦你知道了，请选择。

  Is your signal a differential signal, or is one side grounded? If it's differential, then you should use a differential probe.

According to the datasheet, you have a choice of probes:
- 10076B – 250 MHz, 100:1, 4 kV passive probe
- N2771B – 50 MHz, 1000:1 30 kV passive probe
- N2791A – 25 MHz, 700V differential probe
- N2891A – 70 MHz, 7 kV differential probe

What's the BW of the transient? You can estimate that by using .5/rise time. Once you know that, take your pick.

我不知道BW我被告知测量将在一辆卡车内部吹扫一些LED，他们认为这是因为交流发电机或其他地方的高瞬态。
它让我觉得褶皱可以产生那些高瞬态，它会先调节稳压器而不是显示器中的某些LED，它们是否可以达到高电压？
面对一种你不知道有多高的瞬态可以保护探头和设备的情况下，最好的方法是什么？

     以下为原文

  I dont know the BW I was told the measurements will be inside a truck that blows some LEDs in a diplay and they think is because high transients from the alternator or somewhere else. It srikes me that a tuck can generate those high transients, would it blow the regulator first and not some LEDs in a display and can they be that high in voltage?
What is the best approach when facing a situation where you dont know how high trasients can be in order to protect the probes and equipment?

Sorry again for the repeated messages I had a problema with my browser, I fixed it. I cant delete my repeated messages.
