Low noise, programmable DC power supplies offers precision measurement

Available now from Farnell element14, the Series 2280S Precision Measurement, low noise, programmable DC power supplies from Keithley/Tektronix 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 Model 2280S-32-6 can output up to 32V at up to 6A; the Model 2280S-60-3 can output up to 60V at up to 3.2A. Unlike conventional power supplies, the supplies can also make measurements with up to 6½ digits of resolution. Voltage output measurements can be resolved down to 100µV. These supplies measure load currents from 100nA to amps and can resolve down to 10nA. To monitor fast-changing and pulse-like load currents properly, the supplies offer the speed necessary to capture load changes that occur at intervals as short as 140µs. The bright, 4.3-inch TFT display shows voltage and current readings, the source settings and many additional settings in large, easy-to-read characters. The icon-based main menu provides all the functions users can control and program for fast access to source setup, measurement setup, display formats, trigger options, and system settings.
