2182A

The two-channel Keithley 2182A Nanovoltmeter is optimised for making stable, low-noise voltage measurements and for characterising 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 2182A represents the next step forward in Keithley nanovoltmeter technology, replacing the original Keithley 2182 and offering enhanced capabilities including pulse capability, lower measurement noise, faster current reversals, and a simplified delta mode for making resistance measurements in combination with a reversing current source, such as the 6220 or 6221.

Flexible, Effective speed/Noise Trade-offs

The Keithley 2182A makes it easy to choose the best speed/filter combination for a particular application’s response time and noise level requirements. The ability to select from a wide range of response times allows for optimising speed/noise trade-offs. Low noise levels are assured over a wide range of useful response times, e .g ., 15nV p-p noise at 1s and 40-50nV p-p noise at 60ms are typical.

Reliable Results

Power line noise can compromise measurement accuracy significantly at the nanovolt level. The Keithley 2182A reduces this interference by synchronising its measurement cycle to line, which minimises variations due to readings that begin at different phases of the line cycle. The result is exceptionally high immunity to line interference with little or no shielding and filtering required.
