答案是肯定的 - 对所有问题。
我要说的一个澄清是带宽通常用一些额外的信息来定义。
例如,在许多应用中,人们谈论3dB带宽,其通常被定义为跨度,其中S21响应的边缘比S21的最大值低3dB。
使用VNA,您当然可以扫描跨度(超过3 dB角)以获得LNA能够放大的频率范围的完整画面。

the answer is yes - to all the questions. The one clarification, I would make is that bandwidth is typically defined with some additional information. for example in many applications people talk about the 3 dB bandwidth, which is normally defined as the span, where the edges of the S21 response are 3 dB lower than the max value of S21. With the VNA, you can certainly over-sweep the span (go further past the 3 dB corners) to get a complete picture of range of frequencies that the LNA is capable of amplifying.
