This document provides an updated description of a software application that was developed to control a set of Pentek 7631 dual channel high speed interface cards for the purpose of collecting data from a Sea Giraffe radar. Analysis of data collected using the original application showed that a fourth data channel needed to be added to the system to allow for antenna pointing direction to be accurately determined. This document includes the original description of the installation of the Pentek cards, their connection to the Sea Giraffe radar, and the usage of the software. In addition, the documentation now includes the details related to the fourth data channel. The system simultaneously records the in-phase, quadrature, and trigger signals. The fourth data channel is intended to be used to sample azimuth control pulse or azimuth reference pulse signals. A description of how the four-channel data is stored and unpacked is also given.
