Important info on the tinySA Ultra

The tinySA wiki is slowly being updated with info regarding the tinySA Ultra. The names tinySA4 and tinySA Ultra refer to the same device.

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

Introduction and other videos

A short 7 minute video introducing the main features of the tinySA can be found here.

A user has created an very extensive introduction video to the tinySA Ultra which can be found here

Manual

For those that prefer to read a document instead of browsing a wiki, there are two options.
Kurt Poulson was so kind to write an extensive document explaining various aspects of the tinySA for a Danish Amatuer Radio magazine. The English version can be found here. Kurt describes the operation of the signal generator and spectrum analyzer functions and explains how to update the FW. The document contains many screen captures of example measurements.

A second option is a PDF version of the wiki, which allows for easier reading for some people, that can be found here
