ADCMT DC Voltage Current Source/Monitor 6253

Best for development or evaluation of high-precision electronic components by wide source range and 6½-digit measurement resolution

The DC voltage current source/monitor 6253 is suitable as power source for evaluation of semiconductors and other electronic components and as power source of characteristic systems. In addition to high accuracy, high stability and low noise of our strengths, the 6253 realizes higher precision features such as 5½ digit source resolution, 6½-digit measurement resolution and basis accuracy of ±0.02 %. Furthermore, the 6253 can support various applications by the sweep functions, high-speed pulse measurement function with a minimum pulse width of 25 μs, the variable integration function and the newly adopted variable slew rate function.
