The Beagle 480 Power Protocol Analyzer, an addition to the Total Phase equipment portfolio, provides high performance cost-effective real-time analysis, current and voltage monitoring, plus the option of advanced state-based triggering. These features enable correlating USB data transactions with current and voltage measurements. Such trouble-shooting techniques can help identify and locate excess power consumption, which can lead to optimizing the code and circuitry for a more efficient USB embedded design.
Figure 1: Beagle 480 Power Protocol Analyzer- The Beagle USB 480 Power analyzer captures both USB data and power measurements in real time. The 256 MB hardware buffer can capture larger pre-trigger volumes of data.
- The advanced (optional) state-based trigger system with eight non-sequential states and six data matches per state, is similar to the technology of the Beagle USB 5000 v2 analyzer series.
Figure 2 shows an example of a power measurement, which can be viewed with Data Center Software.
Figure 2: Current Voltage Capture
- The red trace of Figure 2 indicates voltage.
- The blue trace indicates current.
There are two versions of the Beagle 480 Power Protocol Analyzer: Standard and Ultimate Edition. Both versions provide the following:
- Real-time graphing of VBUS current and voltage values
- Interactive and bi-directional correlation of current/voltage values with USB data
- 256 MB capacity
- Large circular buffer
In addition, the Ultimate Edition of the Beagle USB 480 Power Protocol Analyzer provides:
USB 2.0 Advanced Triggering Capabilities- Create state-based and flexible trigger conditions based on data patterns, packet types, error types, events, and other criteria
- Hardware packet filtering
- Up to eight independent states and six matches per state for USB 2.0 captures
- Digital inputs and outputs to synchronize with oscilloscopes or logic analyzers
