Series 2280S Precision Measurement, Low Noise,
The Series 2280S Precision Measurement, Low Noise, Programmable DC Power Supplies are much more than just sources of clean power; they are also precision measurement instruments. They can source stable, low noise voltages as well as monitor load currents over a wide dynamic range from amps to nanoamps. The 2280S-32-6 can output up to 32 V at up to 6 A; the 2280S-60-3 can output up to 60 V at up to 3.2 A. 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.

Capture measurements with either an external control signal or an analog level threshold crossing
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 140µs.
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 and a power-down sequence. Measurements can be made as fast as 2500 readings per second, making it possible to characterize and test the current draw at each of the start-up states.
