Abstract
The purpose of this document is to discuss applications of the antenna-level buffering capability being implemented in SKA-LOW. In addition to their scientific motivation -- to detect and study cosmic rays interacting in the atmosphere -- these buffers provide access to low-level data for engineering and development work. Experience has shown that antenna-level buffered data can assist with antenna calibration, localising RFI, and diagnosing fundamental hardware problems. In this document, we describe several of these applications, with close reference to experience with LOFAR, ACTA, Parkes, and the OVRO-LWA.
