Silicon Investigations HP 4140B pA Meter/DC Voltage Source Repair Service

The HP (Agilent, Keysight) 4140B pA Meter / DC Voltage Source component measurement system consisting of  an extremely stable picoampere meter and two programmable DC voltage sources.  The 4140B is ideal for making DC characteristic measurements such as leakage current, current/voltage characteristics, and quasi - static C-V measurements.  Silicon Investigations repairs the 4140B and also buys non working instruments.  Occasionally we also have refurbished instruments available for sale.  Please contact us for more information.

The HP (Agilent, Keysight) 4140B systems are known for power supply failures as well as failures in the pA meter.  Some units also had cooling fan failures (a custom HP part).  Please contact us for more information.
