Describe
Keysight‘s mobile communications DC power supply 663xx series provides a number of features suitable for wireless and battery-powered device testing: Excellent voltage transient response can minimize device downtime caused by a large voltage drop on the test line, ensuring the efficiency of the test system; advanced built-in The measurement system can accurately measure the battery current consumption of the device in different operating modes. The features developed by Keysight can support mobile phone manufacturers to detect permanent and intermittent open wire connections.
Keysight 66321B mobile communication DC power supply can provide fast transient response, excellent power supply capability, output resistance programming and accurate measurement functions. Designed specifically for the testing of next-generation digital wireless communication products, the 66321B mobile communication DC power supply can provide a new function of simulating the internal resistance of a battery or battery pack. In addition, regardless of the application of short or long load lines, these high-performance power supply models have improved transient response and stable output operation.
Combined with the application of 66321B and Keysight 14565B software, R&D engineers can use up to 1000 hours of data recording, CCDF statistical analysis and waveform capture to characterize battery output current and balance the factors that affect current consumption and battery life.
