Introduction

These getting-started guidelines are intended to facilitate the first use of the Beagle USB 480 Power Protocol Analyzer. The Beagle USB 480 Power analyzer can be used with the Data Center Software or the Beagle Software API to monitor Low, Full, or High-Speed USB 2.0 (up to 480 Mbps) devices. This tool also monitors and graphs VBUS current and voltage values in real time. Use the Beagle USB 480 Power analyzer with the Data Center Software and follow the instructions below to monitor a USB 2.0 device.

All current downloads for the Beagle USB 480 Power analyzer can be found on the product page:
