Description
TinySA Portable Spectrum Analyzer, SEESII Updated V0.3.1 100kHz to 960MHz Portable Tiny Frequency Analyzer MF/HF/VHF UHF Input, 2.8 Inch Touch Screen Signal Generator with ESD Protection Function
Frequency
Range Tiny spectrum analyzer with two inputs, high-quality MF/HF/VHF input for 0.1 MHz-350 MHz, lower-quality UHF input for 240 MHz-960 MHz. Switchable resolution bandpass filters for both ranges between 2.6kHz and 640kHz. Color display showing 290 scan points covering the entire range of low or high frequencies. The tinySA contains all the components of a conventional heterodyne scanning spectrum analyzer.
Built-in
calibration signal generator When not used as a spectrum analyzer, it can be used as a signal generator, MF/HF/VHF sine output between 0.1 MHz and 350 MHz, UHF square wave output between 240 MHz and 960 MHz. Built-in calibration signal generator used for automatic self-test and low-input calibration.
Tiny spectrum analyzers and ESD
function Switchable resolution bandpass filters for both ranges between 2.6 kHz and 640 kHz. Color display showing 290 scan points covering the full range of low or high frequency. Built-in rechargeable battery that allows a minimum of at least 2 hours of portable use. The performance of the latest version 3.1 of 2021 will be more stable and responsive, with a new ESD protection function that allows the product to have a higher anti-static level and longer service life.
PC
Control Connected to a PC via USB, it becomes a PC-controlled spectrum analyzer. The USB interface implements the Serial over USB (CDC) protocol and there is a large set of commands that can be invoked through the serial interface. These commands 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.
