SDR WR-G33DDC ‘EXCALIBUR Pro’ 9 kHz to 50 MHz – Excalibur Basics Video by DK8OK

The New WiNRADIO WR-G33DDC ‘EXALIBUR Pro’ direct-sampling SDR Receiver from 9 kHz to 49.995 MHz, includes a real-time 50 MHz-wide specrtrum analyzer and 4 MHz-wide instantaneous bandwidth available for recording, demodulation and further digital processing. – Low-noise preamplifier – Configurable preselection filters – Filter bandwidth adjustable down to 1 Hz.

As many as 119 different filter combinations can be constructed by the user (91 bandpass, 14 low-pass and 14 high-pass). The front-end employs 34 subminiature electromechanical relays! Three demodulators allow the simultaneous reception of three signal frequencies within the 4 MHz bandwidth. -

The WR-G33DDC Pro Is an advanced version of the WR-G31DDC receiver, offering many additional features and improvements.  - (!! Please See the WR-G33DDC  Basics Video  by DK8OK below)

The WR Software (Version 1.68)  provide an logical user interface.  - There are several spectrum analyzer configurations including the 50 MHz full span with 1.5 kHz resolution. – The DDC down-converted portion is highlighted and can be selected either via keyboard or by the mouse cursor and then displayed in another window, within which three independent receiver channels can exist. – For any channel, the receiver’s selectivity, IF shift, passband tuning, notch, and other functions can be adjusted, and the audio spectrum of the demodulated signal can be observed. – -

(Previous Report of 28/07/2010) – The new WR-G31DDC Excalibur by WiNRADIO, the Perseus and New Gemini by Microtelecom Direct Sampling Receivers, already displayed to Ham Radio Fair in Friedrichshafen 2010 (report of 28/07/2010)

WR-G31DDC Excalibur new Direct-Sampling Receiver by RADIXON Group Pty. Ltd. a fully-owned subsidiary of the Australian company Robotron. Robotron is a privately owned high-technology R&D and investment company, founded in 1983.- In the commercial market, the company operates under its brand name WiNRADiO ©  —- Link to: Radixon Group Pty. Ltd  official  Home-page

WiNRADiO © declares that the  new WR-G31DDC Excalibur receiver’s robust front-end (ndr: no preselectors filters!) is equipped with an ultrahigh-linearity amplifier which result in exceptional strong-signal performance. An advanced “dithering” technique eliminates spurios signals without significantly increasing the receiver’s nois floor. The superior 16-bit 100 MSPS analog-to-digital converter (ADC) provides exceptional performance over an extremely wide range of signals. Frequency range 9 kHz to 49.995 MHz three indipendent channels can be set separately.

Excalibur did not Preselector filters in the RF imput, has only (MW filter) a high pass for medium wave. Excalibur sample at 100 MHz (MSPS), but what really happens tuning signals around the frequency of “Nyquist” (100 : 2 = 50MHz) – [Note]: The figures SFDR (Spurious-Free Dynamic Range) declared by the producer is still about 107 dB. The Image Rejection 90 dB typ, with an MDS of -130 dBm @ 10 MHz/500 Hz BW. (Clik the image to enlarge  Ultra Low Jitter Clock features for the Gemini FPGA)

The new GEMINI receiver features two RF inputs signals simultaneously sampled by the Gemini A/D converter are numerically processed at 200 MSPS/channel by a high speed multichannel digital down-converter implemented in a FPGA of Xilinx’s most recent Spartan6 family – Ultra Low Jitter Clock for the Highest Dynamic Range up to VHFs! (including the value of SFDR – Spurious-Free Dynamic Range) – Each of the two RF front-ends are equipped with a six bands pre-selection filters bank ranging from 28 to 170 MHz. —- Link to: Microtelecom srl >Gemini official web-page

Preliminari Specificatons (typical at 145 MHz): RF Imput (2x) – Range 28/170 MHz – Imput IP3 +9dBm – Dynamic Range (500 Hz BW) 100 dB – Blocking DR (500 Hz BW) 123 dB – Internal Reference Clock 400 MHz TCXO – PC Interface USB2 port – Size 210 x 80 x 190 mm (WxHxL)
