CAPABILITY:

The HP 4140B pA Meter/DC Voltage Source provides a stable picoampere meter with a maximum resolution of 10-15 A, and two programmable dc voltage sources. This, along with the programmable hold and step delay function, lets you make synchronized measurements on a device or on material.

Stable, high resolution current measurements: 0.001 x 10-12 A to 1.999 x 10-2 A, accuracy 0.5%, 3.5 digit display

Calculated capacitance range: 0.1 pF to 1999 pF (in two ranges)

Measurement times: ~4 ms to 2.56 s

Zero offset

Trigger: INT, EXT, HOLD/MAN

Input terminal: Triaxial

Measurement functions: I-V, C-V, I
