Keysight / Agilent 34420A Overview

The Agilent 34420A Nano-Volt / Micro-Ohm Meter sets a price/performance standard in low-level measurement capability. The noise performance of the 34420A nano- volt/micro ohm meter is more than an order of magnitude better then previously available from Agilent Technologies.
Low noise input amplifiers and a highly tuned input protection scheme bring reading noise down to 8 nVp-p. Longer integration times improve noise performance even further. A highly-stable current source and the low noise input combine to make outstanding low resistance measurements. A wide range of temperature measurement capabilities are built-in, providing support for SPRT, thermocouple, RTD, and thermistor sensors.
