Keysight Technologies has introduced the X8712A IoT device battery life optimisation software solution, to ensure optimal battery life prior to device deployment to accelerate troubleshooting and device verification.
Many IoT devices today run on battery power. For mission-critical IoT applications such as those in the healthcare and industrial industries, where lives can be at risk due to premature device failure, battery life is more crucial than ever. The challenge falls to IoT device makers to ensure the battery life of their devices will live up to expectations in the real world.
Keysight’s new X8712A solution enables IoT device makers to perform event-based power consumption analysis on IoT devices to gain a better understanding of how they spend their battery charge when operating in real-world conditions.
Design weaknesses can be detected with a wide dynamic-range current measurement and fast 20 µs sampling rate to capture an IoT device’s dynamic current consumption for a specific radio frequency or direct current event. It then automatically correlates that event to the device’s current consumption to easily identify the subsystems or events requiring optimisation.
Battery life can be optimised by calculating the RF or DC event’s occupancy time and current consumption contribution in percentage. By specifying the battery capacity and area of interest, the software estimates battery life based on the device’s charge consumption, so necessary steps can be taken to improve battery life.
