DC Power Source

Responding to changing cellular-telephone designs and battery technologies, Hewlett-Packard Co. introduces its second-generation mobile communications DC power source.

The HP 66311A is a battery-replacement, power source and measurement solution that enables wireless test engineers to test any cellular phone and charger functionality.

The instrument features 5A peak current and a +15 VDC supply. Two user-programmable compensation ranges ensure stable sourcing over a wide variety of wireless product input-capacitance and load-lead configurations.

A combination of command-processing times of less than 4 µs, and output-programming-response times of less than 200 µs achieves fast throughput.
