March 5, 2014 - Innovative Integration announced the 90401 Digital Receiver that provides integrated digital down- conversion (DDC), FFT, spectrum monitoring, and digital beam-forming functions. The solution consists of three parts: An FPGA-based analog digitizer module, a PC-based host controller plus an optional firmware development kit to allow customization. The 90401 Digital Receiver has eight Independent DDC Channels and one 32K FFT for Digital Receiver/Recording, Spectrum Analysis, Surveillance, or Software Defined Radio. A development kit is available to support creation of advanced custom firmware. The digitizer module is provided with software examples and C++ API, plus pre-compiled firmware bit image and a comprehensive manual.
The module may be installed onto an XMC-PCIe adapter to allow use within a conventional PC. Alternately, it can be used within Innovative's Andale Data Recorders to capture extremely long time sequences. Or, the module may be installed within an Innovative ePC or VPXI-ePC embedded computer to create a miniature, self-contained instrument. Regardless, the application software may be used to capture and analyze the data immediately – a turnkey solution.
