The WiNRAD10 WR― G33DDC ttcaribur PrOris a high‐

perforrnance,low口cost,direct口sampling,sofmarettdefined,

shortwave receiver wvith a frequency range frorr1 9 kHz

to 50 MHz.itincludes a real‐宙me 50い 胡Hzowide spectrum

analyzer and 4 MHzコ wide instantaneous bandwidth

available ibr recording,demodulation and further digital

processingB

The receiveris superior perforrnance results from its

innovative,direct―sampling,digital down―conversion

architecture along with the use ofleading‐edge

components and design concepts.These a‖ resultin a

very high iP3,vvide dynarYliC range,high sensitivity and

accurate tuningo These key f●atures create a receiverin

a ctass ofits own,wvith wide application potential,at a

very attordable price.

bandwidth is available fbr recording and demodulationロ

Three demodulators aliow the sirYlultaneous reception of

three signalfrequencies within the 4 1MHzロ

The rec9iveris robust front―end is equipped with an ultra‐

higholinearity amplifier which results in exceptional

strongosignal perforrnance.This already robust front‐end

is further enhanced with a user口selectable preselector

that can operate eitherin a fu‖y automatic or user‐configurable rnodeコAs rnany as l 1 9 different filter

combinations can be constructed by the user(91

bandpass,14 iow‐ pass and 14 highBpass)。The front口end

employs 34 subminiature electromechanical relays(rather

than often used but distortion‐prone senliconductorswttches)tO ensure high dynamic rangeロ

A userttselectable low‐noise prearrlplifier provides

additional sensitivity fbr the receiver to be able to extract

even the weakest signals fro打l nOiSe.

An advanced dithering technique elirrlinates spurious

signals without significantly increasing the receivergs

The WViNRADiO G33DDC receiver breaks new ground wRh Rs state―of―

the‐art components,such as a high―perforrnance 1 6-bit100 MSPS

analog‐to‐digital converter.lt connects to a computer via the USB

interface which facilitates receiver control as weH as transfer ofthe 24‐

bit digita‖y down―converted i&C】signal.The receiveris very we‖

shielded againstinterference,making it possible to operate in a noisy

computer environment.

The receiveris supplied wRh an external AC/DC power adapter,working

in iinear rnode to avoid even the siightest possibility ofinterference

emanating from the power supply.

The WVR‐G33DDC sofmare provides an elegant and lo9ical uSerinterface.

There are several spectrurn analyzer configurations including the 50 MHz

fu‖span with l.5 kHz resolution.The fu‖y―zoomable display can be

viewed in eitherthe standard or waterfaH rnode.

The down―converted portion is highli9hted and can be setected either via

keyboard or by the rnouse cursor and then displayed in anothervvindo比

within which three independent receiver channeis can exist.For any

channel,the receivers selectivty lF shit,passband tuning,notch,and

otherfunctions can be adusted,and the audio spectrurn ofthe

demodulated signal can be observed.

The digital down―converter provides 24 selectable output bandwidths

ranging from 20 kHzto 4 MHz.The receivers selectivity can be adiuSted

with l Hz resolution.The bandpass audio filteris iow and high cut-0付

frequencies are graphica‖y adiustable,as is the notch filter and noise

blanker.

The parameters of a‖three independent channeis can be set separately9

a‖owing each to be recorded sirnultaneousty and independently.

Recording and playback are also provided atthe output ofthe digital

down‐converter,where an entire 4 MHz spectrum band can be recorded

foriater demodulation.Pre―buttering prevents signalloss at the start of

a transmission.

in spite of the receiver:s ground―breaking architecture,the soflware sti‖

remains sirnple and intuitive to use,containing aH the features genera‖y

expected in modern receivers such as noise blanking,rnemories,

scheduler,squeich(leVel,voice or noise activated),numerOus tuning

options,and a wide choice of demodulation rnodes,including user―defined

and opttonal DRM modes.
