Mobile, highly dispersed, battery-powered devices exist in most environments; however, the power consumption of these devices is growing faster than their capabilities, resulting in battery run-time as being the critical point in the device's operational life.

Keysight Technologies, Inc. (NYSE: KEYS) has now made available a battery-drain analysis solution. Keysight is the only company that offers this integrated solution for accurate battery-drain analysis and provides the needed testing information required to manage the wide dynamic-current-range utilized by these devices.

Medical device manufacturers need to maximize 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 on-board monitoring equipment will function without failing to ensure safety over many years.

Keysight's N6781A 2-Quadrant Source/Measure Unit for battery drain analysis.

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 analyzer modular mainframe, 2-quadrant source-measure unit, and control-and-analysis software.
