  1. 1. Digital scanning and monitoring receivers Scanning and monitoring receivers with digital implementation Our digital receiver concept based on the Software Defined (SDR) technology, which means to digitize the data as earlier in the signal path as possible and do all of the functionality in digital domain. Before the analog to digital conversion the required analog signal processing contains band limiting and pre-selection, variable amplification and frequency conversion in higher VHF/UHF bands. After the digitization burst memory (FIFO) or digital down-converter (DDC) is used depending on the application which could be a wide-band scanning or narrow-band monitoring reception. Programmable logic (FPGA) is used for on-board data processing and routing before the data is passed to digital signal processing (DSP) algorithm. The whole receiver is handled trough graphical user interface (GUI) which is running on the platform computer. Scanning receiver for 20GHz/sec speed Wide-band converter is used with 14bit 80Msps ADC and FIFO Monitoring receiver for 1-16 channel operation Narrow-band converter is used with 14bit 80Msps ADC and 4ch DDC Windows GUI based man-machine interfaces with remote control capability for system integration www.sagax.hu Rev. 080210 Sagax, Ltd.
