# WB-SG1-8G: reconstructing a signal generator's serial commands

> The WB-SG1-8G project documents the BG7TBL signal generator's serial protocol and implements a browser controller over Web Serial. Its protocol notes specify connection settings, $X...* command framing, frequency and sweep commands, hardware toggles and observed replies. The page controls both output channels and monitors received and transmitted traffic.
