The Keysight Mobile Communications DC Source 663xx series offers several features ideal for testing wireless and battery powered devices. Excellent voltage transient response ensures maximum test-system throughput by minimizing device shutdowns due to significant voltage drops in the test wiring. Built-in advanced measurement system to accurately measure battery current drains when the device operates in different modes, and a Keysight-developed feature that enables cellular telephone manufacturers to detect permanently and intermittently open-sense wire connections.

The Keysight 66321B mobile communications dc source provides fast transient response, exceptional sourcing, output resistance programming, and precision measurement. This product is specially designed for testing next-generation digital wireless communications products. The 66321B mobile communications dc source offers a new capability that simulates the internal resistance of a battery or battery pack. Additionally, these high performance models offer improved transient response and stable output operation with either short or long load leads.

Research and development engineers can characterize current out of the battery and make tradeoffs in design that impact the current drain and battery life by providing data logging (up to 1000 hours), CCDF statistical analysis, and waveform capture when the 66321B is used with the Keysight 14565B software.
