Colibri DDC SDR SDR (Software Defined Radio) HF / 6m

[Tens de ter uma conta e sessão iniciada para poderes visualizar esta imagem]


This small-size receiver is intended to receive signals covering the HF frequency band 0.09MHz to 55MHz, and also (with the help of external filters) to receive frequencies up to 800MHz whilst working together with a PC.

It incorporates direct digital signal sampling by utilising a high speed analogue-digital converter. Such architecture allows the user eliminate additional noise caused by analogue cascades and makes the signal sound more natural and transparent.

The Local Area Network (LAN) interface allows you to use the device remotely and also allows you to connect several receivers to one PC simultaneously.

The ColibriDDC is a great low-cost HF and 6m receiver that makes the absolute most of direct sampling technology.


Main capabilities

- ADC with sampling frequency 125 MHz and 14 bit resolution is used
- Two independent receiving channels with sampling frequencies up to 312 kHz
- Record air stations with the bandwidth to 312 kHz and the opportunity to reproduce it later
- Opportunity to receive in Nyquist zones up to 800 MHz (necessary to set additional external filters)
- Wide spectrum scope up to 60 MHz
- 24 bit audio – DAC for decreasing signal delay
- Connector for controlling external devices, 7 programmable transistor switches
- Interface with PC – local network 100 Mbps
- Low power consumption, 5V 0.64A
- External reference generator input 10 MHz
- Small dimensions W 64 x H 24 x L 112 mm
- ExpertSDR2 receiver’s software

Software

Programa ExpertSDR2 com interface adaptada para o modo de recepção é usado junto com o receptor ColibriDDC. No presente momento, o software funciona no modo de recepção e mantém dois canais independentes com as bandas a 312 kHz. Biblioteca DSP, desenvolvido pela empresa especialista Electronics, permitiu melhorar a qualidade mais elevada para a recepção e a fiabilidade do software. Dois OS são suportadas: Windows 8 e Linux Ubuntu.
