While the existing system multiplexes analogue signals into oscilloscopes, the proposed DWS will digitise the signals near their source for display with a PyQt based application. A proof-of-concept was previously commissioned with 48 channels and demonstrated the system’s feasibility. Further work has since been undertaken to scale the system up to the full capacity of 480 signals. In the full test system, acquisitions are timestamped using precise timing provided by a White Rabbit network. Additionally, a configuration service for the system was implemented. The scaled-up test system is compared with the existing AWS. Whilst it is primarily designed as a replacement for the AWS, the modular architecture makes it flexible enough to fulfil different potential purposes and work with different technologies. This last point is discussed with respect to other proposed upgrades for the ISIS accelerator controls system. PB - JACoW Publishing CP - Geneva, Switzerland ER -
