Spectrum Analyzers are very useful if you work with radios. Unfortunately, they are very expensive. Until recently, when I saw this small device for around 50$. Unbelievable. But is it any good? In this video, we will: - See, what such a spectrum analyzer does and how it works - Have a close look at this cheap device and compare its readings with a more expensive one - See the difference between spectrum analyzers (SSA3032X), Vector Network analyzers (N1201SA), and SDR radios I am a proud Patreon of GreatScott!, Electroboom, Electronoobs, EEVblog, and others.
