Data Acquisition Program

To sample wideband IF signal with large amounts of data, a high-speed data acquisition program is presented. The program focus on circuit design, issues that need attention, and high-speed sampling signal deceleration strategy. The 2.4GHz rate sampling data acquisition, reception and demux are completed with ADC083000 and Field-Programmable Gate Array (FPGA). At last, a result of sampling with the converter is offered by chipscope software. The result verified ADC083000 has an excellent performance with more than 6.5 bit ENOB and good phase coherence. In engineering practice, the design has been used and has good performance.

The interface presented in this paper is recommended for high speed data acquisition systems; it performs a synchronized sampling of all common-mode or differential analog inputs with a high sampling rate. This is a low cost interface, entirely controlled by the PC104 CPU. Programmable electronic modules that contain such PC104 interfaces can be found running in the energetic system from Romania; these dedicated equipments perform the analog and digital signal acquisition for monitoring and recording different specific transient events. Some experimental results obtained using the disturbance monitoring device PC-08/104 are also presented in this paper.

To improve data transmission performance of the data acquisition card, a design of high-speed data transmission system is proposed in the thesis. Using FPGA of programmable logic devices, adopting Verilog HDL of hardware description language, the design of modularization and DMA transmission method is implemented in FPGA. Eventually the design implements the data transmission with high-speed through PCI Express interface. Through simulation and verification based on hardware system, this design is proved to be feasible and can satisfy the performance requirements of data transmission in the high-speed data acquisition card applied in high-speed railway communication. The design also has some value of application and reference for a universal data acquisition card.
