Typical applications:

Semiconductor

measurements

Gate leakage or channel

leakage in FET-based com-

ponents can generate errors

in MOSFETs, JFETs, analog

switches, and many other

circuits. By allowing research-

ers to measure extremely

low-level currents and voltag-

es, the Model 6430 can help

them understand the design

limitations of these components and investigate alternative device structures or materials.

SET research

The Model 6430’s superior low current measurement ability (0.4fA p-p noise typical) makes it

extremely useful for single electron transistor (SET) and quantum-dot research. Using a technique

similar to a lock-in, the 6430 can measure currents with 1aA sensitivity (10–18A = 6 electrons/second).

The Measurement Industry’s lowest Noise and Drift

This data illustrates the Model 6430’s impressive stability over a five-hour period, as well as its low

short-term noise performance. This signal trace was acquired using the instrument’s AUTOFILTER

with a 5-second rise time on the 1pA range. The inset close-up is a snapshot of the filtered signal,

showing the Model 6430’s low noise during the first 100-second period. The data was taken in a

laboratory environment where temperature varied about 1°C, with the instrument’s IN/OUT HI and

SENSE leads capped.
