PERSEUS - SDR Receiver for VLF-LF-HF

PERSEUS
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 400 kHz. By clicking on
individual stations within this spectrum, they can be selected for
listening in unprecedented quality.
What’s 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.

PERSEUS is capable of displaying the
full spectrum from 10 KHz to 40 MHz with a resolution bandwidth of
10 kHz and a dynamic and spectral purity comparable to the best
spectrum analyzers available on the market. That function PERSEUS
was developed special software for Windows, HFSPAN, given that came
with your receiver.
Software
HFSPAN
PERSEUS is a SDR receiver and use PC
software to make the process of demodulation. The compatibility and
support of application software most used by radio amateurs are provided
by a DLL library for the Microsoft Windows operating systems.
Another
software used to demodulate the signals is
WINRAD of I2PHD
Coming soon: within the next few weeks a version of
CODE300-32 SDR with
the full control and integration of PERSEUS will be available.
