The SR2000A is a frequency Monitor with a five-inch TFT color display, DSP (Digital Signal Processing), FFT (Fast Fourier Transform), and optional APCO25 (P25) decoder. It provides faster sampling rates, color imaging, video display function, and continuous coverage from 5 MHz to 3 GHz (blocked for cellular in the US consumer version). It is designed for base, mobile, or field use and can also be used with a personal computer. The SR2000A is ultra-sensitive, incredibly fast, and easy to use.
