Perseus SDR HF Receiver
Pretty Excellent Receiver for Software-Eager Unperceivable Signals
SDR Receiver for VLF-LF-HF
PERSEUS is a VLF-LF-HF receiver made by Microtelecom is based on a outstanding direct sampling digital architecture. It features a 14 bit 80 Ms/s analog-to-digital converter with an exceptional 76 dB SNR (BW = 40 MHz), an high-performance configurable FPGA digital down-converter with an up to 1 MS/s output sampling rate and a 480 MBit/s, high-speed USB 2.0 PC interface. Unlike in lower class direct sampling receivers, the PERSEUS RF analog front-end has been carefully designed for the most demanding users and includes a 0-30 dB, 10 dB steps attenuator, a low-loss 10 bands pass-band RF preselector filters bank, and an high dynamic preamplifier with a top-class input third-order Intercept Point of more than 30 dBm. The resulting third-order dynamic range is 103 dB for SSB signals (2.4 KHz BW) and 107 dB for CW signals (500 Hz BW).
PERSEUS is a so-called software-defined receiver. This means central properties of reception, demodulation, use and usability are all controlled by the software. One example for this would be filters protecting the signal from interference. In place of just a few filters, each for only a specific narrow bandwidth, as has been standard so far, now the software itself filters the reception signal. This allows listeners to tailor bandwidth exactly to each interference condition, modulation and operating mode with no further need for purchasing additional filters or sacrificing reception quality during filter selection.
But what makes PERSEUS truly revolutionary is a real-time frequency display capable of spanning a spectrum of up to 1600 kHz. By clicking on individual stations within this spectrum, they can be selected for listening in unprecedented quality.
Whats more, the entire frequency spectrum can be saved to hard drive. In effect, this permits listening to anything within that spectrum of up to 400 kHz later on. On top of this, it is also possible to further adjust the spectrum after recording. Another part of PERSEUS is a waterfall diagram used for visual tracking of all activity within a spectrum of even up to 40 MHz over an extended period of time.
