怎么测量使用Fieldfox脉冲源的频率和频段扩展

有没有办法测量（使用Fieldfox）脉冲源（如WiFi）的频率和频段扩展。
我不认为我的N9918A有时间门控选项。
我所看到的只是偶尔的飙升。

  Is there a way to measure (with the Fieldfox) the frequency and band spread of sources that pulse such as WiFi. I do not think my N9918A has the time Gating Option.  All I see is the occasional spike.
