How PowerScale works

Real power consumption measurement

PowerScale is measuring the real power consumption of an application: current and voltage at the same time! A PowerScale system consists of the base unit and at least one probe to be connected to a target. Up to four probes can be connected to measure independently from each other. PowerScale synchronizes the measurement results and displays them within the integrated GUI. This allows for optimizing selected software events and thereby reducing the power consumption of the application.

Adaption to an application

Each of the four PowerScale probes can be connected to different power domains within your application. Additionally the power usage of selected regions of software can be measured. Each software region must provide triggers to the PowerScale probes.  The triggers can be from simple IO, UART or from a suitable debugger. The PowerScale measurements are displayed as a line graph of power, current or voltage against time. The software region information is displayed as a pie chart showing overall power consumption per software region.

Measurment in USB or Ethernet powered applications

For devices powered over Ethernet, an adapter with measurement points for power consumption measurement is avilable. It connects to a network and to the target via standard Ethernet cables.

A similar solution is available for USB powerewd applications. This adapter connects via USB-A to the host and via USB-B to the target.
