• Optimized for battery-powered device testing • Ultra-fast transient response to load changes • 5A continuous output • Pulse peak, average, and baseline current measurements • 100nA DC current sensitivity MODEL 2304A • 100W output (20V @ 5A) • Sinks up to 3A MODEL 2303 • 45W output (15V @ 3A, 9V @ 5A) • Sinks up to 2A The Model 2303/2304A Power Supplies provide both voltage control and power consumption moni­toring for automated testing of portable, battery-operated devices. These power supplies are optimized for testing battery-operated, wire- less communication devices such as cellular phones that undergo substantial load changes for very short time intervals. These power sup- plies exhibit outstanding voltage stability during pulse load changes and can simultaneously measure load currents, even if they are short pulses. In addition, this family of power supplies can sink current and, thus, take on the characteristics of a discharged, rechargeable battery for testing chargers and charger-control circuitry.
