1. NC 10 LaDVIEW Channelizer Solution lt a X NOVATOR SOLUTIONS Why Channelize Spectrum monitoring and signal analysis have many application areas both civilian and military As wireless technologies are becoming more common the RF spectrum gets more crowded and having the right tools to analyze the signals becomes more important By using channelization techniques it is possible to use a single wideband receiver and still analyze thousands of signals Processing Power For online monitoring applications the channelization must be done continuously in Real Time and without disrupting the incoming wideband signal The more extracted channels the more processing power is needed and for high channel counts it is impossible for software based solutions to keep up with the incoming data if a single processing computer is used By using an approach where hardware is tailored for the task such as with an FPGA the channels can be extracted efficiently and uninterrupted www novatorsolutions com NC 10 FPGA based Channelizer Novator Solutions Channelizer NC 10 is an FPGA based solution that gives you the possibility to extract up to 1024 channels in Real Time and stream the channels for further processing NC 10 is powered by ChannelCoreFlex Technology from RFEL LTD UK PXle System Software Customer Application Configuration Configuration Hardware Wideband Data The system is very flexible and unlik2.
