National Instruments PXI PXI-4130 Source Measure Unit

The NI PXI-4130 (Part Numbers: 779647-30 and 779647-31) is a programmable, High Control S Ource Measure Unit (SMU) in a single slot, 3U PXI module. It has a single, separate SMU channel that provides a four-quadrant ± 20V output that consolidates the remote sense (4-wire). This channel is suitable for generating up to 40 W in quadrants I and III and sinking up to 10 W in quadrants II and IV. With five currents giving an estimation resolution of up to 1 nA, this accuracy source is perfect for design validation and semiconductor test applications that require automatic sources and sweep and additional high-precision estimates.

The PXI-4130 also incorporates a utility channel that can generate current or voltage with a 16-bit set point and estimation resolution. This output provides up to 6 V and 1 A, as a supplementary power supply to the SMU channel. Applications such as transistor characterization that require an accurate source of a constant current or voltage while releasing another current or voltage can benefit significantly from the decreased complexity, space, and cost that this module offers.

The two channels of the PXI-4130 Power SMU can act as either a constant voltage source or a constant current source, with a configurable consistency constraint for either mode. Additionally, the user can enable remote sensing on the SMU channel to increase the voltage output / estimation accuracy on the PXI-4130 SMU under test for high precision applications.

The PXI-4130 can be controlled either from the inside from the PXI’s rear panel or remotely via an auxiliary DC supply associated with the front plate, such as the NI APS-4100.
