集群使命将调查的各种地球物理等离子体包含频率范围从直流到100千赫兹以上的波，其中既有磁成分，也有电成分。这些波的特征持续时间从几毫秒延伸到几分钟，并且期望超过90 dB的动态范围。所有这些因素使得波浪实验联合会仪器的机载控制系统必须灵活，以便有效利用有限的航天器能源和遥测信息带宽。数字波处理实验（DWP）将作为WEC的一个组成部分在集群卫星上飞行。DWP将协调WEC测量，并进行粒子相关，以便直接研究波/粒子相互作用。DWP仪器采用了一种基于使用具有并行处理和可重新分配任务的晶片机的新型架构，以提供高可靠性系统。DWP团队的成员还提供了先进的电气地面支持设备，供WEC在开发和测试期间使用。这在Pedersen等人（本期）中有进一步描述。
The wide variety of geophysical plasmas that will be investigated by the Cluster mission contain waves with a frequency range from DC to over 100 kHz with both magnetic and electric components. The characteristic duration of these waves extends from a few milliseconds to minutes and a dynamic range of over 90 dB is desired. All of these factors make it essential that the on-board control system for the Wave-Experiment Consortium (WEC) instruments be flexible so as to make effective use of the limited spacecraft resources of power and telemetry-information bandwidth. The Digital Wave Processing Experiment, (DWP), will be flown on Cluster satellites as a component of the WEC. DWP will coordinate WEC measurements as well as perform particle correlations in order to permit the direct study of wave/particle interactions. The DWP instrument employs a novel architecture based on the use of transputers with parallel processing and re-allocatable tasks to provide a high-reliability system. Members of the DWP team are also providing sophisticated electrical ground support equipment, for use during development and testing by the WEC. This is described further in Pedersen et al. (this issue).
