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
