The Red Pitaya is marketed as a type of digital oscilloscope, and is more accurately described as a type of digital measurement and control tool that sells for about $220 USD. However the technology behind its operation (high speed ADCs) is basically the same as what is used in a software defined radio like the RTL-SDR. By using the correct software, and by reconfiguring it’s onboard Xilinx FPGA, the Red Pitya can be turned into an SDR transceiver.
Until recently SDR projects for the Red Pitaya have been rare and so Pavel Demin decided to create his own. So far he’s managed to create a dual channel SDR transceiver that is compatible with SDR#, HDSDR, GNU Radio as well as with HPSDR. It can tune from 0 – 50 MHz with a bandwidth of up to 500 kHz, sampling with its 14-bit ADC.
More information on setting the Red Pitaya up as a SDR transceiver with software like SDR# and HDSDR can be found on Pavels website.
