Unfortunately, I don't know enough to be able to write a really good description, so here's a link to the official TINYSA website:

Welcome to the tinySA® wiki!

WARNING: Be aware of bad quality copy products, see where to buy

The tinySA are a small spectrum analyzers and signal generators with some nice capabilities:

  • tinySA Basic
    • Screen size 2.8 inch
    • Spectrum Analyzer with two inputs, high quality MF/HF/VHF input for 0.1MHZ-350MHz, lesser quality UHF input for 240MHz-960MHz or
    • Signal Generator with two output, sine wave output for 0.1MHz - 350MHz and square wave output for 240MHz-960MHz when not used as Spectrum Analyzer.
    • Switchable resolution bandpass filters for both ranges between 2.6kHz and 640kHz
    • Color display showing max 290 scan points providing gapless covering up to the full low or high frequency range.
  • tinySA Ultra
    • Screen size 4 inch
    • Spectrum Analyzer for 0.1-800MHz or, with Ultra mode enabled, level calibrated up to 6GHz. Can observe signals up to 12GHz
    • Signal Generator with sine wave output between 0.1-800MHz or square wave up to 4.4GHz or rf test signal output up to 5.3GHz when not used as Spectrum Analyzer.
    • Switchable resolution bandpass filters from 200Hz to 850kHz
    • Built-in 20dB optional LNA
    • Color display showing max 450 points providing gapless covering up to the full frequency range.
    • MicroSD card slot for storing measurements, settings and screen captures. 
  • Input Step attenuator from 0dB to 31dB (can not be used in combination with LNA).
  • A built-in calibration signal generator that is used for automatic self test and (low) input calibration.
  • Connected to a PC via USB it becomes a PC controlled Spectrum Analyzer or Signal Generator
  • Rechargeable battery allowing a minimum of 2 hours of portable use
  • Max input level +10dBm. Do not destroy your tinySA
  • The generator function can not be used as a tracking generator as you can not use the spectrum analyzer and generator functions at the same time.
  • Due to the low cost and very small form factor there are certain relevant tinySA limitations and tinySA Ultra limitations
