| New nanovoltmeter for eliminating noise in low voltage measurements
Keithley's new Model 2182A Nanovoltmeter is optimized for making low noise measurements in research, metrology, nanotechnology, superconductivity, and other low voltage/resistance applications. Use it with the models 6220 DC current source or 6221 AC/DC current source to make resistance measurements, pulsed I-V measurements, and differential conductance measurements faster and more accurately than previously possible, in many cases eliminating the need for an expensive lock-in amplifier or AC resistance bridge. The combination is also useful in many nanotechnology applications because of its ability to measure resistance while dissipating very little power in the device under test (DUT).
Device testing and characterization for today's very small and power-efficient electronics requires sourcing low current levels, which demands the use of a precision, low current source. Lower stimulus currents produce lower - and harder to measure - voltages across the device. Combine the Model 6220 or Model 6221 with a Keithley Model 2182A Nanovoltmeter to address both of these challenges.
