One of the objectives is to limit the frequent recharging of batteries and maximise their lifespan. Knowing the AC\/DC energy consumption of objects also makes it possible, depending on their use, to size ambient energy recovery technologies (solar cell, motion, electromagnetic, etc.) to create energy-independent objects. This test bench provides a wide range of measurement options for improving the design of objects to enhance their performance and guarantee their reliability.<\/p>\n<h5>\n<style type=\"text\/css\"

consumed by a system or the sub-systems of a complex object.<br \/>\n- Measure current and voltage accurately over a wide dynamic range depending on the object's operating status (on, standby, communication, etc.).<br \/>\n- Measure accurate power consumption with sufficient bandwidth to avoid missing fast-moving digital events.<br \/>\n- Synchronise the energy consumption measurement with the powered object's software subroutines to optimise processor programming and maximise the object's battery life.<br \/>\n- Correlate load consumption with RF events and events in the object's sub-circuits.<br \/>\n- Examine the impact of power consumption as a function of RF interference with other wireless devices in a real or controlled environment by combining it with the telecommunications test bench (influence of the channel model, RF disturbances, interferers, electromagnetic pulses, etc.).<br \/>\n- Testing in difficult electromagnetic environments (C2EM: anechoic chamber, reverberation chamber)<br \/>\nAssessing the characteristics of a device's battery<br \/>\n- Visualise the evolution of the power consumed by an object as a function of its use and record it over a long period in a points file.<br \/>\n- Replay a recorded points file to check the performance of a battery and estimate its lifespan.<br \/>\n- Characterise the charging and discharging of a battery over time.<br \/>\n- Statistical analysis (CCDF) of power consumption.<\/p>\n<p><strong>\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\"
