The tinySA ultra is a handheld 100 kHz - 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.
