[Frequency Range]:Compared to the tinysa (100kHz to 960MHz), the upgraded tinysa ULTRA has 100kHz to 5.3GHz ultra-wide measuring frequency range, spectrum analyzer for 0.1-800MHz, with Ultra mode up to 0.1MHz-6GHz. Switchable resolution band pass filters for both ranges between 200Hz to 850kHz. Color display showing 450 scan points covering up to the full low or high frequency range. Faster and more accurate measurement performance, you can easily cope with measurement testes in various fields. This Version V0.4.5.1 Spectrum Analyzer with 4.0 inch 480 x 320 large touchscreen display, 100kHz to 5.3GHz widely measure range, with the ESD protection function, the product has a higher anti-static level and a longer service lifecan directly record data to the card ,which is convenient for your data sharing and storage. [2 in 1 Multifunctional Frequency Analyzer & Signal Generator]:When not used as Spectrum Analyzer it can be used as Signal Generator,with sine wave output between 0.1-800MHz or square wave or dual tone output up to 4.4GHz. Built-in calibration signal generator that is used for automatic self test and low input calibration. [PC Control]:Connected to a PC via USB it becomes a PC controlled Spectrum Analyzer or Signal Generator. Tinysa-APP transfers data directly to the computer. The USB interface implements 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. [200Hz-850kHz RBW]:The RBW is as low as 200Hz, which can effectively distinguish adjacent signals and meet the requirements of SSB dual-satellite inter-modulation test. Input Step attenuator from 0d
