Evaluate Battery Run-Down Performance of Mobile Devices
应用文章
The Keysight Technologies, Inc. 66319D and 66321D mobile communications DC sources are specialized products ideally suited for directly powering and measuring current drain on many mobile wireless devices. Together with the 14565B device characterization software, they provide an easy way of performing long-term battery current drain measurement and analysis.
There are also times when it is advantageous to use a battery instead of the DC source to power the mobile device. This application note describes a detailed procedure on how this solution can also be used to easily and accurately evaluate performance of the mobile device while being directly powered by its battery. This greatly simplifies a task that is normally time consuming and cumbersome when using traditional approaches.
