Feature: 1. Signal Generator: Sine wave output between 0.1 and 800MHz, or square wave or dual tone output when not used as spectrum analyzer, up to 5.3GHz. 2. Resolution Switchable: Band pass filter with switchable resolution for two ranges between 200Hz and 850kHz. 3. PC Connection: Connect to PC through USB, and the analyzer will become a PC controlled spectrum analyzer or signal generator. 4. Calibration Signal Generator: There is a built in calibration signal generator, used for automatic self test and (low) input calibration. 5. 0dB to 31dB: Input stepped attenuator, from 0dB to 31dB (not used with LNA). Built in 20dB, optional LNA. The color display screen displays 450 scanning points, covering the entire frequency range. 6. Portable: Comes with a small size and lightweight, 2 hours portable use allowing you to take this analyzer with you to help with your work.
