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. DMM-Quality Low Current Measurements with High Resolution Unlike conventional power supplies, Series 2280S supplies can also make measurements with up to 6½ digits of resolution. Voltage output measurements can be resolved down to 100 µV. 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.
