High-speed digitiser
20 July 2011
Test & Measurement
SP Devices has introduced a high-speed digitiser boasting 12-bit resolution at a 3,6 GSps sample rate with up to 2 GHz of analog bandwidth. The ADQ412 is a 2/4-channel instrument which enables demanding measurements such as RF/IF sampling of very wideband signals.
The analog front end is AC-coupled and optimised for spectral purity over a wide bandwidth. The lower cut-off frequency is as low as 30 kHz and the bandwidth is set by the mode of operation. The digitiser connects to the host via a high-speed USB 2.0 cable or through an optional Compact PCI Express/PXI Express interface. All interface types allows for streaming of data at high transfer rates.
The ADQ412 comes with an easy-to-use API for integration into any application. Software tools for application development include C/C++, Matlab and DLLs for Windows XP/Vista. The SDK also includes SP Devices’ data capture tool, ADCcaptureLAB.
The digitiser is built on the ADQ DSP computational board which employs a Xilinx Virtex 6 LX240T FPGA. The user can access the FPGA and implement customised digital signal processing by purchasing the ADQ development kit. This kit contains everything that is needed to get started with the FPGA development, including examples and documentation.
Standard trigger options are external, software and level trigger. The ADQ412 supports single and multiple records. The multiple records mode can be combined with any trigger function. A time stamp function tags each record with timing information.
SP Devices offers the possibility of customising the ADQ series digitiser boards. Customisations can include hardware, software and FPGA firmware changes.
