Specification: * Display resolution 320*240 pixels * Screen diagonal 2.8" * 16 bits per RGB pixels * Resistive touch control * Jog switch control * USB serial port control * Optional TTL USART port (SW not yet implemented) on the internal PCB * Linear power supply to avoid switching noise.

The performance of the 2021 latest version 3.1 TinySA spectrum will be more stable and sensitive, with a new ESD protrcted function enable the product to have a higher antistatic level and a longer service life.

Spectrum Analyzer with two inputs, high quality MF/HF/VHF input for 0.1MHZ-350MHz, lesser quality UHF input for 240MHz-960MHz.

Switchable resolution bandpass filters for both ranges between 2.6kHz and 640kHz

Color display showing 290 scan points covering up to the full low or high frequency range.

Input Step attenuator from 0dB to 31dB for the MF/HF/VHF input.

When not used as Spectrum Analyzer it can be used as Signal Generator, MF/HF/VHF sinus output between 0.1MHZ-350MHz, UHF square wave output between 240MHz-960MHz.

The USB interface implements the Serial over USB (CDC) protocol and there is a large set of commands that can be invoked over the serial interface. These command can be used to perform measurements or update internal settings. The driver for Windows will install automatically after connecting to a Windows PC. The driver for Linux is built into the kernel
