Keithley 2308 Battery/Charger Simulator

Overview

The Keithley 2308 Portable Device Battery/Charger Simulator is optimized for testing mobile phones and other battery-operated portable devices. It features rapid response to load changes so that when a device transitions from sleep or standby mode to full power transmission, there is minimal transient voltage drop and quick recovery. This fast response is essential for proper device operation during testing and helps prevent production yield problems caused by slow-responding conventional power supplies.

Key Features

• Dual-channel output: 0 to 15 V DC with optimized current ratings for portable devices
• Ultra-fast response to pulsed load operation for accurate battery simulation
• Speed-optimized command set reduces test times and improves throughput
• Variable output resistance for simulating actual battery output response characteristics
• Battery simulator channel capable of sinking up to 3 A
• Dedicated charger supply for testing charge control circuits
• Pulse peak, average, and baseline current measurements
• Integrating A/D converter for precise measurement accuracy
• 100 nA current measurement sensitivity
• Analog output for complete load current waveform characterization
• Open sense-lead detection for immediate wiring problem identification
• Built-in digital voltmeter
• Four built-in digital control lines for test automation

Applications

• Mobile phone design and production testing
• Portable device battery management testing
• Pulsed mode device operation verification
• Charger circuit performance validation
• Sleep-to-active mode transition testing
• Production testing of battery-powered components
