The two-channel Model 2182A Nanovoltmeter is optimized for making stable, low noise voltage measurements and for characterizing low resistance materials and devices reliably and repeatably It provides higher measurement
speed and significantly better noise performance than alternative low voltage measurement solutions The Model 2182A represents the next step forward in Keithley nanovoltmeter technology, replacing the original Model 2182 and offering enhanced capabilities including pulse capability, lower measurement noise, faster current rever-sals, and a simplified delta mode for making resistance measurements in combination with a reversing current source, such as the Model 6220 or 6221.
flexible, Effective speed/Noise Trade-offs
The Model 2182A makes it easy to choose the best speed/filter combination for a particular applica-tion’s response time and noise level requirements The ability to select from a wide range of response times allows optimizing speed/noise trade-offs Low noise levels are assured over a wide range ofuseful response times, eg, 15nV p-p noise at 1s and 40-50nV p-p noise at 60ms are typicalFigure 1 illustrates the Model 2182A’s noise performance.
