Keithley 2306-PJ Dual-Channel Battery/Charger Simulator

Overview

The Keithley 2306-PJ is a dual-channel battery and charger simulator optimized for development and production testing of portable, battery-operated products such as cellular phones, cordless telephones, mobile radios, and pagers. The instrument simulates both a battery's output voltage and output resistance, allowing devices under test to perform identically to operation with actual batteries. One channel simulates battery discharge (with current sinking capability), while the other provides a charging supply.

Key Features

• Dual-channel output: 0-15V with variable output current (0-4V: 5A max; >4V: IMAX = 60W/(VOUT+6))
• Ultrafast transient response for accurate battery simulation
• Variable output resistance for emulating actual battery response characteristics
• Pulse peak, average, and baseline current measurements
• 100 nA DC current sensitivity for precise current measurement
• Current step measure function for transient analysis
• Sink up to 3 A for simulating discharged rechargeable battery conditions
• Open sense lead detection
• Built-in digital voltmeter
• GPIB interface for automated test systems

Applications

• Cellular and cordless telephone design and testing
• Mobile radio development
• Battery charger circuit validation
• RF power amplifier testing in low-power devices
• Rapid device transition testing (standby to high-power transmission)
• Portable device power consumption profiling
