Digitizer PCI-Express Card Signatec PX1500-4

Signatec advertise through Instrumentos de Medida, s:L.,  the high speed digitizer card PX1500-4, the card A / D high bandwidth for more advanced PCIe market. Synchronized capture four channels at frequencies up to 1.5 GHz, or two channels synchronized to an incredible frequency of 3 GHz when the four interleaved A / D converters

Memory 2GB on board FIFO configured as x8 PCIe bus and say the PX1500-4 can hold logs up to 1.4 GB / s in continuous mode through x8 PCIe bus (both mechanically and electrically) to storage systems PC without breaking the analog record.


Real-time processing
Two Virtex ® -5 FPGAs embedded control the functionality of the card with DSP resources and optionally with signal processing in both online customized chips.
As a member of the Xilinx Alliance Program, Signatec create data interfaces and standardized control client accessible by the VHDL source code examples that demonstrate how to use these interfaces simplify the tasks of real-time processing through its firmware development kits optional.
The PX1500-4 was designed to maximize the quality of the captured signals in terms of Signal to Noise Ratio (SNR) and Spurious Free Dynamic Range (SFDR) over a wide frequency range. Having the family of Virtex-5 FPGAs to provide real-time processing and growing set of development libraries for programming FPGAs offered Signatec, the PX1500-4 becomes an exceptional tool for engineers in aerospace, defense and intelligence.

Sampling rate selectable between 200 MHz and 1500 MHz
Beyond its high speed and multi-functionality, the clock frequency of the synthesized PX1500-4 to adjust the ADC sampling frequency to any value between 200 MHz (the minimum ADC clock frequency allowed) up to 1500 MHz, providing great flexibility to select the sampling frequency. The additional circuitry "Divide-by-2" provided even lower sampling frequencies. This flexibility to select frequency does not reduce the quality and performance of the acquisition clock when adjusting the internal reference clock of 10 MHz / 5 PPM or an external reference clock of 10 MHz ADC can also be controlled by a clock source external.
Users no longer need to adapt or limit the clock frequency for their applications. This feature is ideal for low-Nyquist sampling where the band needs to be perfectly tuned to correctly locate the center frequency of the signal to be recorded in half the Nyquist zone and thus optimize the total bandwidth or data captured.
Segmented Mode The time recording 'Time-Stamp' to store the temporal relationship between memory segments. The 'Time Stamps' are 64-bit values with a resolution of 4/fADC clock and accumulate in a FIFO memory 2048 separate items of data. If necessary, time records can be read during data acquisition to prevent excess flow of data. This is possible in any mode of acquisition.


System configurations synchronized with six cards
Up to three PX1500-4 cards can be interconnected in a master / slave configuration using a ribbon cable. In this configuration the clock and trigger signals from the card direct master slave cards so that the sampling data of all cards is performed simultaneously. Using SYNC1500-6 as a source of clock and trigger for the system can operate up to 6 cards completely synchronized, where the 6 cards can even be mounted on different PCs This scalability allows increasing the ratio of data per channel for logging applications High-speed signal and / or real-time processing.
The new Signatec PX1500-4 is one of the high-speed digitizer cards with better performance on the market today. This broad Signatec more so the speed with which you can acquire, process and store data on their registration systems turnkey hardware which include parallel digital processing systems, massive data storage and generation of form arbitrary waveform. Signatec designs and manufactures technology systems in real-time signal for applications in advanced radar, SIGINT, ultrasound, Picture and other applications of high-speed communication.
