Characterizing the Battery Usage of a Pulse Oximeter, Step by Step Instructions

Designers of medical devices need an accurate way to determine the battery life of their product.
The current needs of a device can vary greatly between sleep, idle, and active states. An Agilent N6705B DC Power Analyzer with a N6781A Source Measure Unit along with the 14585A software can be used to accurately measure the dynamic current. Battery life can be determined and often improved by charactering the dynamic current. In this video step by step instructions are provided for characterizing a Pulse Oximeter dynamic current.
