The Perseus 22 is a 4 Channel, Direct Sampling SDR Receiver with continuous frequency coverage from 10 KHz to 225 MHz and a typical image rejection larger than 70 dB.
All 4 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. This allows for 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 is 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 Reflective, Black Surface Treatment.
