| 摘 要： | 近年来世界VLBI（Very Large Baseline Interferometry）终端技术发展迅速，主流的记录终端已发展到Mark5B记录系统，Mark5C也正在研制和测试阶段。为了适应未来高速率、海量数据以及数字基带转换器观测的要求，需要将现有的Mark5A升级到Mark5B或Mark5B＋，相应地需要将Mark4格式器升级为MarkB采样器。主要描述了相关设备的原理以及Mark4格式器升级的步骤。

| Abstract: | The VLBI terminal technology is developing rapidly over the world in recent years. Recording systems of the Mark5B type are installed in increasingly more stations, while the Mark5C type is under development and tests. In order to meet future requirement of high-speed recording, massive-data storage, and observations with DBBC, we need to upgrade the Mark5A to Mark5B or Mark5B ＋. Accordingly, a Mark4 formatter needs to be upgraded to a Mark5 sampler module. This paper describes the principle of relevant devices and the procedure of the upgrade of a Mark4 formatter. |
