The two-channel 2182A is optimised for making stable, low noise voltage measurements and for characterising low-resistance materials reliably and repeatedly. It provides higher measurement speed and better noise performance than alternative low voltage measurement solutions. The ability to select from a wide range of response times facilitates optimising speed/noise trade-offs. Low noise levels are assured over a wide range of useful response times, typically 15nV p-p noise at 1s response time and 40-50nV p-p noise at 60ms.

• 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
