SP Devices has announced its latest ADQ series digitizer. With a 1.1GSps real-time sampling rate and 12bits resolution, the unit claims the best-performing combination of high speed and high resolution on the market today. The ADQ 112 is the second digitizer in the ADQ family that uses SP Devices' proprietary interleaving technology for achieving high sample rates. It provides 1GHz input bandwidth and allows for deep data captures through the up to 512Mbyte of onboard sample memory. Several interface standards are supported, including PXI Express and USB.

The digitizer comes equipped with a Xilinx Virtex 5 FPGA dedicated for customer-specific real-time signal processing.

"We realized that a traditional digitizer is not sufficient for many of today's demanding test and measurement requirements," said Stefan Ahlqvist, senior product manager at SP Devices. "Instead, customers show a strong demand for the ability of including their own real-time DSP as part of the data acquisition process. Typical processing added by the customer includes peak detection, decimation, filtering and averaging."

The FPGA development kit is sold separately, while a software development kit that provides quick and flexible access to the ADQ 112 through Matlab, LabVIEW, C/C++ or dynamic link libraries is included free of charge.

With its combination of customizable hardware, flexible software components, high sample rates and high resolution, the ADQ 112 suits applications such as wireless communications, test and measurement, signal intelligence, and radar processing.
