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 66319D dual output mobile communications dc source provides two outputs for testing both the main battery power and the battery charger circuitry, allowing customers to test phones and chargers with the same equipment. This feature helps save on rack space (2 outputs in a _ rack box) and eliminates the need for two separate power supplies. The 66319D dc source provides all of the capabilities of the 66319B with the addition of a built-in digital voltmeter.

For R&D engineers, you 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 66319D is used with the Keysight 14565B Software.
