Abstract

This paper presents a radiation hardened digital oscilloscope tailored for space applications. The waveform capture system (WCS) was designed as a data acquisition system for a time of flight instrument on the European Rosetta cometary mission. The WCS is a radiation hardened low power, single board solution, providing 11 bits of accuracy, sub-nanosecond resolution, and complete command and data handling. This paper details the design and evolution of the WCS, as well as presenting results from recent testing of the engineering qualification module with the time of flight instrument
