Data acquisition and record system plays an important role in signal processing. For the wideband signal acquisition and processing application, such as 3G/4G Base Stations, Wideband Microwave Backhaul, Military Communications, and RADAR, the need for high speed and smart software-defined radio (SDR) test platform is growing. In this paper, we implement a high compact form factor data acquisition and storage system used for the wideband signal application development. In order to implement high compact, low power and high speed real-time data storage, we use a PCIe-based switch architecture and leverage the Flash array as the storage part. The system supports RF sampling directly and offers a 16TB solid state storage module which could be read and write at the sustained speed of 12.8GB/s.

Based on the theory of ultrasonic testing, an online data-acquisition and storage system is designed. The design scheme of hardware and software of the system is introduced in this paper, in which the embedded processor DSP and FPGA is used as its control core and the interface of PCI bus and DSP is designed. Thus a high speed and large-capacity ultrasonic signal can be processed, furthermore the pipelines defects can be analyze and evaluate.

Along with the rapid development of computer technology, high speed data acquisition and storage system has been widely applied in plenty of engineering fields, such as radar, aerospace industry, communication, etc. In order to satisfy the increasing requirement, we present the design structure of a novel integrated instrument for ultra-high speed data acquisition and storage, which is composed of ultra-high speed data acquisition, high speed data transmission and solid storage three main sub-systems. The detailed design and realization of the sub-systems are presented. We test and analysis the performance of the integrated instrument and the actual results show that the instrument performs stably and provides excellent speed and precision.

The design of high speed data acquisition and storage system is based on Labview. It can not only achieve high accuracy and high data rate but also use the software and hardware synchronization trigger to complete the multi-channel continuous real-time monitoring of the acquisition and storage periodic signal. Which is similar to the function of the oscilloscope. This system is based on high speed data acquisition card of NI company and Labview 2012 for PC software development platform. Data acquisition card is used to finish data acquisition of periodic signal through the serial port. It also collect data upload to upper computer. Upper computer collect data for storage display and analysis to realize the real-time monitor of multi-channel analog. The design of the sampling channel is 2, the sampling rate up to 200M/s, the sampling precision is 12 bits, and the sampling depth is 2000. Lots of verification prove that the design has good compatibility, performance and stability of the collection. Data error is negligible by analyzing the data collected. More importantly, the design can be as far as possible to restore the actual signal source data without distortion. This paper provides a portable design for high speed data acquisition, which can be widely applied in the engineering of modern test and measurement technology.

This article focuses on research and implementation of a kind of solid storage system that is based on NAND flash which can store the data with high speed and huge capacity. A design with quad 1.25Gsps ADC and flash storage array with 1TB is demonstrated in the paper. The design is applied widely in many fields such as radar, communication and speech recognition. The detail of hardware development is also introduced in the thesis. In addition, a method is discussed to approve the reading and writing bandwidth by parallel operations on multiple pieces of flash. By using the method, the data bandwidth is arrived 6GB/S.
