The 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 resulting from significant voltage drops in the test wiring. A built-in advanced measurement system accurately measures battery current drains when the device operates in different modes and a unique feature enables cellular telephone manufacturers to detect permanently and intermittently open-sense wire connections.

The Keysight 66319B dual output mobile communications DC source provides two outputs for testing the main battery power and the battery charger circuitry, allowing customers to test phones and chargers with the same equipment. This saves you rack space (2 outputs in a ½ rack box) and eliminates the need for two separate power supplies.

R&D 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 66319B is used with the Keysight 14565B Device Characterization Software with Test Automation.
