$129 Spectrum Analyzer???


Yes, it’s true. I ordered this ultra low cost analyzer from for a mere $129 just to play and found out that, despite some serious weaknesses, it is actually a useful tool.

There are five models, four single-band units, covering each of the most-used ISM bands (433, 868, 915 MHz and 2.4 GHz), and one model that encompasses all the bands, except 2.4 GHz. The 2.4 GHz band may be retrofitted into the latter for an extra 55 USD. They are all based on Silicon Labs Si4431 receiver chip (240 to 960 MHz). I purchased the model WSUB1G that tunes from 240 to 960 MHz.
