Keysight (formerly Agilent T&M) 4141B DC Source / Monitor

The 4141B DC source/monitor is designed for use as a system component in user-designed semiconductor I-V or DC parametric test systems. It features a wide DC measurement range, high resolution, high-speed measurement capabilities, remote sensing, and high accuracy.

Four source/monitor units coupled with two voltage-source units, two voltage monitor units, and one ground unit make the 4141B equivalent to 21 instruments. A stand-alone instrument capable of measuring dc parameters, the 4141B features high resolution measurements (50 fA/100 µV) and a built-in timing controller. Typical time for a current or voltage measurement, which includes data transfer, is approximately 25 ms. A swept measurement (51 points) takes approximately 490 ms.
