The tinySA ultra is a handheld 1kHz — 6 GHz spectrum analyser which is designed, developed and now sold from Eindhoven, The Netherlands. The tinySA ultra is a follow-up to the tinySA. The differences between these two spectrum analysers are described in the model overview below. Moreover, this device comes with a 4.0-inch resistive touch color display which shows the full frequency range in 450 scan points, and has a rechargeable battery included for up to two hours of portable use. Furthermore, the analyser features two different modes: normal mode and ultra mode. Additionally, the tinySA ultra has many built-in configuration options such as a switchable bandpass filter and a low-input step attenuator. It’s important to keep in mind that the maximum input level of the tinySA is +6 dBm. If you’re unsure about the input level of your signal, it’s recommended to use an attenuator to be on the safe side.
When the tinySA ultra is not used as a spectrum analyser, it can be also used as a signal generator to output sine or square waves.
The analyser can be fully controlled by a PC through a USB cable. It also features an automatic self-test and self-calibration through the built-in signal generator.
The tinySA and tinySA ultra developer has set up a very extensive wiki page with all necessary information, manuals, operating limits, and explanations. This wiki can be found here.
We sell the original version, be aware of many clones in the market!

Support The TinySA ultra is an open-source product with support from the community. Most questions are answered in the Wiki, for further problems you can go here. By default, the ultra mode is disabled, but the ultra mode can be enabled by following the instructions described on the Wiki. Therefore we do not provide technical support on the TinySA ultra. Warranty on the hardware is of course provided by Eleshop.
