Digitiser combines high speed, high resolution

ADQ 112

SP Devices has introduced its latest ADQ series digitiser. With a 1.1GSps real-time sampling rate and 12bits resolution, the digitiser claims the best-performing combination of high speed and high resolution on the market today.

The ADQ 112 is the second digitiser in the ADQ family that uses the company's proprietary interleaving technology for achieving high sample rates. It provides 1GHz input bandwidth and allows for deep data captures through the up to 512MB of onboard sample memory. Several interface standards are supported, including PXI Express and USB.

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

"We realised that a traditional digitiser 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 customisable 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.
