可以使用86100C Infiniium DCA示波器查看用27 GHz载波信号调制的脉冲信号吗

简短的回答是，“也许吧！”
86100及其插件通常针对数字信号进行了优化。
如果你有一个很好的独立时钟，这个时钟是你想要测量的信号部分的已知时间，它可能会起作用。
如果您的信号类似于雷达脉冲，那么您将看到脉冲的形状（包络），但内部细节很少。
这是因为，除非载波与时钟相位相干，否则信号不是真正“重复”的。
如果您有图片或信号草图，那么可能会给您更明确的答案。
我有点偏见，但实时示波器，如DSO83204A，32GHz的BW，以每秒80GSamples的采样，可能是一个更好的解决方案。
它可以一次捕获整个脉冲，查看脉冲中的每个周期，然后甚至告诉脉冲中每个周期的频率。
通过内置的幅度调制功能，您可以获得包络，并进行上升时间，下降时间，下垂（这需要更多工作），PRF等测量... Al免责声明：为了更可靠的响应，

  The short answer is, "Maybe!"

The 86100 and its plugins are generally optimized for digital signals. If you have a good separate clock that is a known time away from the portion of the signal that you want to measure, it might work.

If your signal is something like a radar pulse, then you will see the shape of the pulse (the envelope), but very little detail of the interior. This is because, the signal isn't truly "repetitive", unless the carrier is phase coherent with the clock.

If you have a picture, or a sketch of your signal, then it might be possible to give you a more definite answer.

I'm a little prejudiced, but a real-time scope, like the DSO83204A, with 32GHz of BW, and sampling at 80GSamples per second, might be a better solution. It can capture the entire pulse in a single shot, look at every cycle within the pulse, then even tell the the frequency of every cycle within the pulse. With the built-in Amplitude modulation function, you can get the envelope, and make measurements such a Rise Time, Fall Time, Droop (this takes a little more work), PRF, etc...
