In recent years, data acquisition technology is more widely used in industrial. This paper introduces a data acquisition system based on linux OS. The data transmission follows USB2.0 protocol. The hardware is mainly composed by CY7C68013 and MAX1195. CY7C68013 is a high-speed USB peripheral controller produced by Cypress Semiconductor Corporation. Max1195 is a dual and high-speed analog-to-digital converter. Hardware construction and driver program design of this system are particularly recommended in this paper. This system can be used in electronic test and biological engineering.

Due to the rapid development of manufacturing technology, high-speed high-resolution data acquisition system has been widely applied in plenty of engineering fields, such as radar, environmental surveillance, mass spectrometry, etc. In order to satisfy the increasing requirement, we present the design of a high-speed data acquisition system, which is mainly composed of high-speed time-interleaved analog-to-digital converter, high data throughput interface based on 10 gigabit Ethernet. The detailed design and realization of each module are presented. Finally we test and analysis the performance of the ion signal acquisition system, and the results show that the system performs fine speed, high precision and stability.

Abstract A multi-function digital baseband data acquisition system is designed for the sampling, distribution and recording of wide-band multi-channel astronomical signals. The system hires a SNAP2 board as a digital baseband converter to digitize, channelize and packetize the received signal. It can be configured dynamically from a single channel to eight channels with a maximum bandwidth of 4096 MHz. Eight parallel HASHPIPE instances run on four servers, each carrying two NVMe SSD cards, achieving a total continuous write rate of 8 GB s−1. Data are recorded in the standard VDIF file format. The system is deployed on a 25-meter radio telescope to verify its functionality based on pulsar observations. Our results indicate that during the 30-minute observation period, the system achieved zero data loss at a data recording rate of 1 GB s−1 on a single server. The system will serve as a verification platform for testing the functions of the QTT (QiTai radio Telescope) digital backend system. In addition, it can be used as a baseband/VLBI (Very Long Baseline Interferometry) recorder or D-F-engine of correlator/beamformer as well.
