BitSim has developed an Ultra High-Speed Acquisition Board (UHAB). The UHAB has both analog to digital and digital to analog converters on the board as well as the new large Virtex-4 SX FPGAs. The 2 channel ADC has a bandwidth of 1.7 GHz and up to 1.5 GS/s with an 8-bit resolution (ENOB 7,0-7,4 bits). This makes it capable of continuous acquisition at up to 3.0 GS/s. The analog inputs have adjustable attenuators, so the inputs can be adjusted 0-31 dB in 1 dB steps. Also, there are 2 DACs as well as both optical and copper Gbit Ethernet connection. It also provides other interfaces like RS232, synchronous serial interfaces, a level configurable trigger input and two MMCX connectors.
Memory should not be a problem, since it has SDRAM, Flash memory, an SD-card slot and optional DDR2 memories. Two Xilinx Virtex-4 SX35 (on board) and one Virtex-4 FX12 (on mini module) FPGAs make the board extremely versatile. These FPGAs are connected with a High-Speed link to make data transfer as fast as possible. Two boards may also be interconnected using a 12-differerential-pair connector.
The board requires only 5VDC power, and incorporates temperature monitoring of ADC, DACs and FPGAs. Typical applications include radar, sonar, microwave and general data acquisition systems. For more information on the UHAB-solution, contact us.
