FAQ

Product-specific questions

Product-specific answers based on available technical information.

Does the PXIe-4143 support four-wire sensing?

Yes. Each of its four channels has integrated remote four-wire sensing.

Are the four channels isolated from one another?

The channels share a common LO. They are isolated from earth ground, not independently isolated from each other.

What limits apply when sinking power?

The specifications limit total sinking power to 6 W per module.

What does the 10 pA current figure mean?

The detailed specifications list 10 pA resolution and noise on the 10 μA range over a 0.1–10 Hz bandwidth under stated operating conditions. It is not an absolute current-accuracy specification.
