4140B

Keysight 4140B DC Voltage Source

The 4140B device can be coupled with two DC voltage sources. These sources are programmable. It ensures the user can utilize the 4140B in various application areas. It also has a high stability pA Meter integrated within. It has the resolution of the order of 10ˉ¹⁵A. It has a basic accuracy of 0.5% and covers measurements on large scale. It enables stable pA current measurement. The 4140B device integrates unique and amazing mechanism. It uses it to achieve this measurement stability and accuracy. This technique implemented to measure small leakage currents in semiconductor devices.

The 4140B also enables users to study static characteristics of FET’s. It also helps to measure insulation resistance and capacitance analysis in manufacturing. One of the two voltage sources is also capable of generating staircase and ramp waveforms. These are accurate and have unique characteristics. The 4140B DC voltage source has the output range of 100 volts in 100 mV steps. It also offers separate auto and manual sweep modes to users. The DC voltage sources also have built-in current limiter. It avoids DUT from damage due to excessive current.

The 4140B product provides users with most accurate current and voltage measurements. It can synchronize measurements timing between voltage source and meter section. The model 4140B compliances to International Electromechanical Committee safety requirements. The 4140B has the ZERO offset on the front panel. It compensates errors for pA meter.

The trigger lamp is also built in 4140B DC voltage source or pA meter. It provides synchronization with measurement on I.C display. It also has range selection key on the front panel. It selects the ideal value of current is auto mode. In manual mode, the change in the value of current does not have any impact on measurement range.
