The Fobos SDR is a high-performance Software-Defined Radio (SDR) receiver with a USB 3.0 interface. This device offers a continuous operating frequency range from 100 kHz to 6 GHz and up to 50 MHz bandwidth with 14-bit signal sampling resolution, ensuring full data integrity. With two auxiliary input channels, HF1 and HF2, for coherent direct sampling and a primary RF reception channel, Fobos SDR provides flexibility and precision in signal reception. Support for an external clock input, straightforward driver installation, and wide compatibility with popular software such as SDRSharp, HDSDR, and GNURadio make Fobos SDR an ideal solution for hobbyists, researchers, and professionals in the field of radio communication seeking to leverage the capabilities of SDR technology fully.
