As battery life becomes more and more critical in today’s devices, Keysight Technologies announced the availability of a battery-drain analysis solution that delivers insight into critical applications for the energy, automotive and medical device industries.
A multitude of mobile, highly dispersed, battery-powered devices exist in such applications. Often their power consumption is growing faster than their capabilities and this results in battery runtime as the critical point in the operational life of a device.
Medical device manufacturers need to maximise battery life on monitors and sensors that interact directly with the human body and its functions. Energy companies often locate battery-powered devices remotely to collect information from water, gas and electric meters. Automotive engineers must confirm that onboard monitoring equipment will function without failing to ensure safety over many years.
Mobile, battery-powered devices often transition between sleep current, idle current pulses and active current pulses when in full transmit mode. Measuring low current and pulsing current with fast rise and fall times over a wide dynamic range is difficult. Previous available tools failed to provide accurate measurements when the current signal rapidly changes and the current varies depending on what tasks the device and sub-circuit is performing.
Keysight’s integrated solution for battery-drain analysis includes a DC power analyser modular mainframe, 2-quadrant source-measure unit, and control and analysis software.
