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 reversals,
and a simplified delta mode for making resistance measurements in combination
with a reversing current source, such as the Model 6220 or 6221.
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
