RPG/RDA Build Training

WDTB has delivered training on the WSR-88D Radar Product Generator (RPG) and Radar Data Acquisition Unit (RDA) since the system was initially fielded. The courses below present the new functionality, system changes, and their impacts to users for each build release.

Training Access

The links on the left access the course information pages for each build release. You can access an outline of the significant build changes by moving your mouse over each of these course info page links.

The links on the right are for the various training content that is available. NOTE: The streaming lessons and documents for a particular build release will contain similar information. We recommend you pick the format you prefer to find the information you are looking for in that particular training lesson.
