ADC board with 8GB deep RAM achieves >70dB dynamic range

LISTED UNDER:

Ultraview Corporation has announced an ultra-fast PCIe data acquisition board allowing uninterrupted acquisition of two concurrent 2 GSPS 12-bit A/D channels or a single channel at up to 4 GSPS. The AD12-2000x2's unique combination of proprietary low-noise, low-distortion DC-2 GHz front end, fast (40ns) trigger latency, deep 8GB on-board memory, and ability to be driven from either a fixed internal clock or an external clock (which may be rapidly-swept over the entire 300 to 2000 MSPS range for applications such as OCT), enables new capabilities in communications spectroscopy, SIGINT, surveillance, missile testing, RADAR and other defense, scientific, and medical applications.  When installed in any x16 PCIe slot (x8 or x16 electrical), the AD12-2000x2 can acquire data at an aggregate rate up to 8 GB/sec, optionally process it in the on-board Virtex FPGA, buffer it in the 8GB on-board RAM, and continuously stream the data via 1.4GB/sec PCIe x8 DMA transfers to host system RAM, for immediate use, graphical display, or storage to disk.

Low latency rapidly-retriggerable acquisition
A low-latency ECL/PECL/edge external trigger input enables sampling to start within 40ns of the trigger and a synchronized selective recording feature allows acquisition to then be dynamically stopped and started in response to a TTL input, increasing effective memory depth by storing only the needed data, for RADAR, NMR, burst communication, pulsed-spectroscopy and other applications.  The board can automatically acquire specified lengths bursts of data ranging from 4 Gigasamples down to blocks of only a few kilosamples repeatably triggered even at rates of millions of bursts per second with only  a few samples dead time between bursts.

TTL Inputs concurrent with sampling, for precise time correlation of analog and digital events
The board can also sample up to four TTL signals concurrently with, and at half the sampling rate of, the  analog sampling, for time-locked correlation of the analog data with TTL fiducial signals, such as RADAR antenna position, sweep generator retrace, etc.

Wide-range External Clock (accepts rapidly-swept OCT clocks) as well as Fixed Internal Clock with programmable divide (decimation).

The AD12-2000x2 supports external clocks of 300 MHz to 2000 MHz.  It also has a fixed 1 GSPS (2 GSPS on a single channel) internal clock.   A software-controllable on-board decimation capability enables the board to be used at selectable fractions of its 1GSPS/2GSPS internal clock or an external clock.   For example its 1GHz internal clock can be used to effectively sample at 1GSPS, 500MSPS, 250MSPS or 125 MSPS/channel.

Rapid Development and OEM-customization using easily modifiable, Linux/Windows cross-platform C-Software/VHDL-Firmware packages included with board
Designed for operation in critical OEM applications, the AD12-2000x2 allows either straight data acquisition, requiring no user development, or in-line FPGA dataflow processing using the on-board Xilinx Virtex FPGA. 

For use as a standard data acquisition board the supplied user software and device driver allow users to acquire and view data “right out of the box”. Drivers, user software, and example user source code are supplied for both 64-bit Linux and 64bit and 32-bit Windows 8/7/VistaTM/XP. Graphical waveform display software, and routines to store data to disk are included with all boards, in C-language source and ready-to-run executable form. A complete, high visibility, LabVIEW control panel display for both 64-bit and 32-bit windows is also included. The AD12-2000x2 shares a modular Front-end Mezzanine architecture with Ultraview’s complete line of 8, 12, 14 and 16-bit A/D boards, enabling a common software platform for all models. Also, the acceptance of fast external clock sweep rates is common to other OCT-capable Ultraview models, such as its dual 14-bit 20 to 400 MHz sweepable AD14-400x2 or its dual 8-bit 500-to-1800 MHz AD8-1800x2 boards.

The AD12-2000x2's supplied VHDL firmware source lets users optionally modify the board's supplied standard data acquisition firmware to perform advanced application-specific hardware signal processing, including filtering, sub-band tuning, averaging, spectroscopy, SDR and image processing.  This modular VHDL firmware source is available to OEM users at no charge under NDA.

Low total System pricing. Standard PCIe x16 format allows installation in low-cost system
Pricing in quantity of 1-4 boards is $15,995 for AD12-2000x2-8GB-8GB-50T ($14,995 for 1.8/3.6GSPS version: AD12-1800x2-8GB-50T).  Availability: Stock.
