Low noise programmable DC power supplies are more than sources of clean power

The Keithley 2280S Series 2280S precision measurement, low noise, programmable DC power supplies are now available from Farnell element14. They 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 device makes 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. The bright, 4.3-inch TFT display has an icon-based main menu providing all the functions users can control and program for fast access to source setup, measurement setup, display formats, trigger options, and system settings.
