66321D

The Keysight 66321D mobile communications DC source provides fast transient response, exceptional sourcing, output resistance programming, and precision measurement.

The Keysight 66321D 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 66321D 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. The 66321D dc source provides all of the capabilities of the 66321B with the addition of a built-in digital voltmeter.

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 66321D is used with the Keysight 14565B software.

Overcome Battery Powered Device Testing Challenges

Digital communications devices and digital battery-powered devices present a unique testing challenge: they draw rapid pulses of current. By offering superior transient performance, unmatched in the marketplace, the Keysight Mobile Communications DC Sources dramatically reduce the transient voltage drop caused by the pulse loading of digital communications devices. The Keysight Mobile Communications DC Sources enable you to maximise test throughput by minimising test interruption due to false trigger of device low voltage shutdown due to transient voltage drops.

Dynamic Measurement Capabilities

The Keysight Mobile Communications DC Sources offer a built-in advanced measurement system to accurately measure battery current when the device operates in different modes (such as talk mode, active mode, standby mode, and off/sleep mode). Measurements made during these modes are critical for ensuring that your devices are operating properly and that you are getting the most out of the battery.
