Product Introduction:
The two-channel Keithley 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 Keithley 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 reversals, and a simplified delta mode for making resistance measurements in combination with a reversing current source.
Features:
Make low noise measurements at high speeds, typically just 15nV p-p noise at 1s response time, 40-50nV p-p noise at 60ms
Delta mode coordinates measurements with a reversing current source at up to 24Hz with 30nV p-p noise (typical) for one reading. Averages multiple readings for greater noise reduction
Synchronization to line provides 110dB NMRR and minimizes the effect of AC common-mode currents
Dual channels support measuring voltage, temperature, or the ratio of an unknown resistance to a reference resistor
Built-in thermocouple linearization and cold junction compensation
Flexible, Effective Speed/Noise Trade-offs:
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 optimizing 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
