abstract = {{The SLAC ATCA Scope, a 4-channel dual scope, has an EPICS support package that runs on top of SLAC’s Common Platform software and firmware, and communicates with several high-performance systems in LCLS running on the 7-slot Advanced Telecommunications Computing Architecture (ATCA) crate. The software was completely refactored to improve the usability for IOC engineers. Once linked with an EPICS IOC, it initializes the scope hardware and instantiates the upper software stack providing a set of PVs to control the API and hardware, and to operate the oscilloscope. The exported PVs provide seamless means to configure triggers and obtain data acquisitions similar to a real oscilloscope. The ATCA scope probes are configured dynamically by the user to probe up to four inputs of the ATCA ADC daughter cards. The EPICS support package automatically manages available ATCA carrier board DRAM resources based on the number of samples requested by the user, allowing acquisitions of up to 8 GBytes per trigger. The user can also specify a desired sampling rate, and the ATCA Scope will estimate the nearest possible sampling rate using the current sampling frequency, and perform downsampling to try to match that rate. Adding the EPICS module to an IOC is simple and straightforward. The ATCA Scope support package works for all high-performance systems that have the scope common hardware implemented in its FPGAs. Generic interfaces developed in PyDM are also provided to the user to control the oscilloscope and enrich the user’s seamless overall experience. }},
