TinySA Spectrum Analyzer 2.8″ Touchscreen SDRGEEK MF/HF/VHF-UHF

Description

Product Overview

The TinySA Spectrum Analyzer Handheld delivers professional‑grade frequency analysis in a pocket‑size package. Featuring a vivid 2.8 inch capacitive touchscreen, the unit provides intuitive navigation and real‑time spectrum visualization without the need for external monitors. Two dedicated RF front‑ends allow seamless switching between a high‑precision MF/HF/VHF path (0.1 MHz‑350 MHz) and a broader UHF path (240 MHz‑960 MHz), each equipped with selectable band‑pass filters ranging from 2.6 kHz to 64 kHz resolution. An integrated step attenuator (0‑31 dB) on the MF/HF/VHF input ensures accurate signal measurement across a wide dynamic range. The device is powered by a rechargeable lithium‑ion battery delivering a minimum of two hours of continuous operation, and it can be tethered to a PC via USB‑C for extended data logging, firmware updates, and remote control. In addition to its primary function as a spectrum analyzer, the TinySA doubles as a versatile signal generator, offering sinusoidal output on the MF/HF/VHF band and square‑wave output on the UHF band, making it a multifunctional tool for RF development, education, and field diagnostics.

Usage

Designed for engineers, hobbyists, and educators, the TinySA thrives in a variety of environments. Field technicians can deploy the handheld unit for on‑site antenna tuning, interference hunting, and spectrum monitoring in remote locations, thanks to its lightweight chassis and battery autonomy. Amateur radio operators benefit from the dual‑band capability when aligning transceivers, testing filters, or verifying signal purity across the HF and VHF/UHF spectrum. In classroom settings, instructors can demonstrate fundamental concepts of frequency domain analysis, modulation, and signal generation without the overhead of bulky laboratory equipment. The USB‑PC interface enables seamless integration with software tools for data capture, automated sweeps, and custom scripting, expanding its utility for research labs and product development teams. Whether mounted on a portable test bench, carried in a field kit, or used on a laboratory bench, the TinySA provides reliable performance across a broad frequency range, making it an indispensable companion for any RF‑related task.
