Have someone a success story with this spectrum analyzer ?
Have one of these for quick and dirty scans.
Practically worthless without having a notebook connected.
Otherwise, can give some good results and if you are pretty careful with what to press and when, you can record and replay your scans.
Also, software needs somework.
