Details

The tinySA is a handheld 0.1 - 960 MHz spectrum analyser which is designed, developed and now sold from Eindhoven, The Netherlands. The device comes with a 2.8 inch resistive touch color display which shows the full frequency range in 290 scan points, and has a rechargeable battery included for up to two hours of portable use. The analyser features a high (UHF) and a low (MF/HF/VHF) input mode, and various other capabilities. Additionally, the tinySA has many built-in configuration options such as a switchable bandpass filter and a low input step attenuator.

The analyser can be fully controlled by a PC through a USB cable. When the tinySA is not used as a spectrum analyser, it can be used as a signal generator to output sine or square waves. It also features an automatic self-test and self-calibration through the built-in signal generator.

The tinySA developer has set up a very extensive wiki page with all necessary information, manuals, operating limits, and explanations. This wiki can be found here. Dutch vlogger Tony Albus tried the TinySA, you can find his video here.
We sell the original version, be aware for many clones in the market!
