[[File:Rasdr2-case-montage-cropped.jpg|center|550px|Radio Astronomy Software Defined Receiver, top]]<br />
RASDR is an Open Hardware project undertaken by members of the Society of Amateur Radio Astronomers (SARA) to develop a low cost, high performance software defined receiver. The goal of RASDR is to provide a low cost hardware that enables radio astronomers and educational institutions to perform high quality astronomical measurements.<br />
[[File:Rasdr2-case-inside.jpg|center|550px|DigiRED+MyriadRF=RASDR2, top]]<br />
The RASDR device is formed from a combination of a DigiRED interface board interfacing the [[Myriad-RF 1]] to the USB3 bus. The combination of the DigiRED and Myriad-RF 1 boards provides a low-cost receiver platform, based on the flexible, multi-standard Field Programmable Radio Frequency (FPRF) LMS6002D device. It is a finely tuned component for radio amateurs, astronomers and educational institutions that are attempting to make precision measurements of the radio-frequency spectrum.<br />

[[File:659x-Digired-Block-Diagram.jpg|center|550px|DigiRED block diagram]]<br />
Apart from the [[Myriad-RF 1]] board which provides the radio interface, the RASDR device uses a board to translate the digital output of the LMS6002D to USB for access by the host computer. This enables the software defined receiver operation. The design is minimal to support the functionality and to keep production cost as low as possible.<br />
<br />
===Connections===<br />
In addition to those available on the [[Myriad-RF 1]] itself, the RASDR provides the following connections:<br />
* Superspeed USB 3.0, supporting up to 28MHz of signal capture bandwidth<br />
** compatible with USB 2.0, with reduction in maximum bandwidth (10MHz)<br />
* Firmware upload switch<br />
* Reference Clock Input (10MHz, 50ohm) for synchronizing the clock to a facility timing signal<br />
* General Purpose I/O (4 pins)<br />
* Pulse Per Second Input (1 pin), such as one obtains from an external GPS receiver<br />
* +5V output (250mA maximum, when using USB 3.0) for powering external devices such as an up-converter board.<br />
