WiNRADiO WR-G33DDC

WiNRADiO combineert de modernste ontvangertechnologie met de mogelijkheden van een computer (PC). 
Het unieke ontvangstconcept zet de standaard in particuliere en professionele monitoring.
De perfecte synthese van hard- en software leidde tot een duidelijke GUI met een consistent bedieningsconcept.

Het Software-Defined-Receiver (SDR)-concept maakt meerdere en altijd aanpasbare toepassingsgebieden mogelijk, zoals bijvoorbeeld bewaking van de gezichtsveldsterkte, naadloze databaseverbindingen, directe integratie van signaaldecoders of IP-gebaseerde bediening op afstand.

De WiNRADiO G3-Serie (3e generatie) is DRM-compatibel (behalve WR G33EM) en is de ideale instap in de ontvangst van de digitale lange, midden- en kortegolf. 

De bekroonde WiNRADiO WR-G33DDC 'EXCALIBUR Pro' is een hoogwaardige, goedkope, direct-sampling, softwaregedefinieerde kortegolfontvanger met een frequentiebereik van 9 kHz tot 49,995 MHz. Het bevat een realtime 50 MHz-breedspectrumanalysator en 4 MHz-brede onmiddellijke bandbreedte die beschikbaar is voor opname, demodulatie en verdere digitale verwerking.

English version

The award-winning WiNRADiO WR-G33DDC 'EXCALIBUR Pro' is a high-performance, low-cost, direct-sampling, software-defined, shortwave receiver with a frequency range from 9 kHz to 49.995 MHz. It includes a real-time 50 MHz-wide spectrum analyzer and 4 MHz-wide instantaneous bandwidth available for recording, demodulation and further digital processing.

This product is an advanced version of the WR-G31DDC receiver, offering many additional features and improvements, such as for example:

• 4 MHz instantaneous processing bandwidth
• Low-noise preamplifier
• Configurable preselection filters
• Filter bandwidth adjustable down to 1 Hz
• 0.5 ppm frequency stability
• Test and measurement functions
• Pause function

The receiver's superior performance results from its innovative, direct-sampling, digital down-conversion architecture along with the use of leading-edge components and design concepts. These all result in a very high IP3, wide dynamic range, high sensitivity, and accurate tuning. These key features create a receiver in a class of its own, with wide application potential, at a very affordable price.

The entire 4 MHz DDC (digitally-down-converted) bandwidth is available for recording and demodulation. Three demodulators allow the simultaneous reception of three signal frequencies within the 4 MHz bandwidth.

Features

• 9 kHz to 49.995 MHz continuous frequency range
• Direct sampling
• Digital down-conversion
• 16-bit 100 MSPS A/D converter
• 50 MHz-wide, real-time spectrum analyzer
• 4 MHz recording and processing bandwidth
• Continuously adjustable filter bandwidth down to 1 Hz
• Three parallel demodulator channels
• Pause function
• Waterfall display functions
• Audio spectrum analyzer
• Audio and IF recording and playback
• Recording with pre-buffering
• EIBI, HFCC and user frequency databases support
• Networking version of application software available
• Very high IP3 (+31 dBm)
• Excellent sensitivity (0.20 µV SSB, 0.10 µV CW)
• Excellent dynamic range (107 dB)Excellent frequency stability (0.5 ppm)
• Selectable medium wave filter
• User-configurable preselector
• Selectable low-noise preamplifier
• Test and measurement functions
• USB 2.0 interface

The receiver's robust front-end is equipped with an ultra-high-linearity amplifier which results in exceptional strong-signal performance. This already robust front-end is further enhanced with a user-selectable preselector that can operate either in a fully automatic or user-configurable mode. 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 (rather than often used but distortion-prone semiconductor switches) to ensure high dynamic range.

A user-selectable low-noise preamplifier provides additional sensitivity for the receiver to be able to extract even the weakest signals from noise.

An advanced dithering technique eliminates spurious signals without significantly increasing the receiver's noise floor. The superior 16-bit 100 MSPS analog-to-digital converter provides exceptional performance over an extremely wide range of signals.
