Perseus22 is a 4 channels, direct sampling receiver with a continuous frequency coverage from 10 KHz to 225 MHz and a typical image rejection larger than 70 dB.
All channels are synchronously sampled by an high SNR, 14 bits A/D converter and processed by a software defined digital down converter, implemented on an FPGA, which outputs are routed to the host PC by a USB 3.0 controller, allowing wide-bandwidth IF applications. The frequency coverage is split-up in 2 groups of channels (two for VLF-HF frequency range, the others for VHF), each one capable of diversity, which can reduce noise or null an interfering signal.
All channels include an analog RF frontend equipped with attenuators, preselection filters and amplifiers.
The receiver enclosure is machined from solid aluminium and finished with a fine, non reflecting, black surface treatment.
Perseus 22 management software is born from the new team formed by Elad and Microtelecom developers, both with years of experience in developing software for DSPs.
It features a simple and intuitive graphical interface, being at the same time efficient and complete.
The GUI is build using OpenGL, which make possible to leverage the GPU for everything related to the rendering of controls and windows, keeping CPU take care exclusively of digital processing of radio signals.
Thanks to the libraries used, Perseus22 management software is portable to other operating systems such as Linux, MacOS and even Android with little effort.
