[Frequency Range]:Compared to the (100kHz to 960MHz), the upgraded 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. This New Version V0.4.5.1 Spectrum Analyzer with 4.0 inch 480 x 320 touchscreen display, 100kHz to 5.3GHz widely measure range, with the new ESD protection function, the product has a higher anti-static level and a 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. For -APP transfers data directly to the computer. The USB interface implements CDC protocol and there is a commands that can be invoked over the serial interface. These 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 . [200Hz-850kHz ]:The is as low as 200Hz, which can effectively distinguish adjacent signals and meet the requirements of SSB dual-satellite -modulation test. Input Step attenuator from 0dB to 31dB (can not be used not in combination with LNA).
