Graviton TinySA Spectrum Analyzer V0.3.1 100KHz-960MHz

Handheld Spectrum Analyzer 100 kHz–960 MHz

The Graviton TinySA V0.3.1 is a portable spectrum analyzer covering MF, HF and VHF bands from 100 kHz to 350 MHz and a UHF input from 240 MHz to 960 MHz. It fits engineers, hobbyists and field technicians who need a battery-powered instrument for quick signal checks. The color display presents 290 scan points across the selected span. Switchable resolution bandpass filters adjust between 2.6 kHz and 640 kHz.

Upgrade From PC-Based Dongles

This unit replaces tethered USB dongles that require a laptop and external power. The jump is worth it when measurements must be made on a tower, in a vehicle or at a remote site without mains power. Built-in rechargeable cells deliver at least two hours of continuous operation. Automatic self-test and low-input calibration run on the internal signal generator, removing the need for a separate reference source.

Signal Generator And Measurement Headroom

When not analyzing spectra the device acts as a signal generator with sine output from .1 to 350 MHz and square-wave output from 240 to 960 MHz. It comfortably handles AM, FM and narrowband digital signals within the stated filter bandwidths. The UHF input offers lesser dynamic range above 240 MHz, so wideband or very weak UHF signals may fall below the noise floor. Buyers needing tracking generators above 960 MHz or laboratory-grade phase-noise performance should look elsewhere.
