Direct sampling receivers are considered as the "holy grail" of SDR, because the signal is digitized directly after the antenna. The Panoradio SDR (www.panoradio-sdr.de) features a sampling rate of 250 MHz resulting in a 100 MHz aliasing free bandwith for spectrum monitoring and reception from short wave to VHF at the same time. With an additional frontend direct sampling reception of the 70cm band is possible. The SDR hardware is build upon the Zedboard, containing a modern Xilinx Zynq device, that combines FPGA and a dual ARM A9 processor on a single chip. It runs a linux operating system and therefore works in standalone mode - with only a mouse and monitor connected. The purpose of the Panoradio SDR is to demonstrate the capabilities of today's technology for signal monitoring and reception.
