RigExpert Fobos SDR 100 kHz – 6 GHz
SDR receiver from 100 kHz to 6 GHz, 50 MHz bandwidth, 14-bit ADC, USB 3.0, two direct-sampling channels
The RigExpert Fobos SDR is a high-performance software-defined receiver covering 100 kHz to 6 GHz, with 50 MHz of sampling bandwidth, a 14-bit ADC and continuous data streaming over USB 3.0.
Product description
The main receiver covers 25 MHz to 6 GHz continuously with double-heterodyne conversion. Two coherent auxiliary direct-sampling channels cover 100 kHz to 25 MHz and are suited to diversity reception, correlation and phase-difference direction finding.
IQ sampling reaches 50 million samples per second (2 × 25 Msps in direct sampling). Speed, 14-bit resolution and continuous streaming are available at the same time, with no dropped buffers: uninterrupted recording and real-time analysis.
The updated version adds an 8-line GPO port to control external equipment, improves passband response and USB link stability, protects the antenna inputs from electrostatic discharge and adds 24 MHz low-pass filters on the HF1 and HF2 inputs.
The aluminium case is EMI shielded and the sturdy USB 3.0 Type-B socket also supplies power. The software includes an open-source API library (LGPL-2.1), wrappers for SDRSharp, SoapySDR, GNU Radio, SDR++, HDSDR (ExtIO), examples in C, C++, C# and Pascal (Delphi) and native support in µSDR 1.7.1 and later, for Windows and Linux.
