They can source stable, low noise voltages as well as monitor load currents over a wide dynamic range from amps to nanoamps. Both supplies use linear regulation to ensure low output noise and superior load current measurement sensitivity. A high resolution color Thin Film Transistor (TFT) screen displays a wide range of information on measurements. Soft-key buttons and a navigation wheel combine with the TFT display to provide an easy-to-navigate user interface that speeds instrument setup and operation. In addition, built-in plotting functions allow monitoring trends such as drift. These supplies provide the flexibility required for both benchtop and automated test system applications. For example, they provide a list mode, triggers, and other speed optimization functions to minimize test time in automated testing applications. DMM-Ouality Low Current Measurements with High Resolution Unlike conventional power supplies, Series 2280S supplies can also make measurements with up to 6/ digits of resolution. Voltage output measurements can be resolved down to 100 pV. These supplies measure load currents from 100 nA to amps and can resolve down to 10 nA. Four load current measurement ranges (10 A, 1 A, 100 mA, and 10 mA) support measuring a device's full load current, standby mode current, and small sleep mode currents with DMM-quality accuracy. The high resolution allows characterizing small changes in load currents with confidence. It also makes it possible to make a broad range of measurements on a single range with excellent accuracy across both low and high current values.

Series 2280S Precision Measurement, Low Noise, Programmable DC Power Supplies Measure Rapidly Changing Loads To monitor fast-changing and pulse-like load currents properly, Series 2280S supplies offer the speed necessary to capture load changes that occur at intervals as short as 140 µs. This capability allows designers and manufacturers of portable, battery-operated devices to monitor load currents easily in all of a device’s operating modes so they can determine the device’s total power consumption. This high speed measurement capability allows measuring each state of a power-up load sequence...

Series 2280S Precision Measurement, Low Noise, Programmable DC Power Supplies Controlled Rise and Fall Times Protect Devices Under Test Perform Semi-Automated Testing Right on Your Bench Are you working on a device or a system with a high in-rush current? Series 2280S supplies allow programming the voltage output’s rise time to slow the voltage ramp and avoid voltage overshoot, which could potentially damage the DUT. The voltage fall time can also be controlled to prevent a fast ramp down of the output voltage. Voltage rise and fall times can be set as slow as 10 V/s or as fast as 100 V/s. Small...
