摘　　要：随着数据记录速率的提高以及对数据准确性的要求,老的采集系统已经不能满足新的要求,迫切要求采用新的终端和技术。Mark6是麻省理工学院研制的最新的记录终端,已经用于主要的天文机构,比如JIVE、KASI、Max-Planck-Institute等。首先介绍了VLBI数据记录终端的现状,给出了上海天文台对Mark6软硬件的调试与配置;然后介绍了使用Mark6与CDAS2互连进行数据记录的测试及分析;最后对Mark6系统的应用及相关软件的后续研发进行了简洁阐述。可为后续终端采集系统的安装、配置及升级提供指导及参考。With the improvement of the data recording rate and higher requirements to the accuracy of the data, the traditional acquisition system can not meet the new requirements, and it is urgent to use the new terminal and technology. Mark6 is the latest recording terminal that is currently developed by MIT. It has been used by the main astronomical institutions, such as JIVE, KASI, Max-Planck-Institute and so on. This paper first introduces the VLBI data acquisition terminal and provides the debugging and configuration of the hardware and software of Mark6 in Shanghai Astronomical Observatory; Then, the data recording test and analysis of the intereonnection between Mark6 and CDAS2 are introduced; Finally, the application of Mark6 system and the subsequent research and development of related software are briefly described. This paper can provide guidance and reference for the installation, configuration and upgrade of the follow-up terminal acquisition systems.
