The National Instruments PXI-4130 PXI SMU is a programmable, high-power source measure unit (SMU) in a single-slot, 3U PXI module. The NI PXI-4130 has a single isolated SMU channel that offers a four-quadrant ±20 V output that incorporates remote (four-wire) sense. This channel is capable of sourcing up to 40 W in quadrants I and III and sinking up to 10 W in quadrants II and IV. With five current ranges providing measurement resolution down to 1 nA, this precision source is ideal for design validation and semiconductor test applications that require programmatic sourcing and sweeping as well as high-accuracy measurements.

The PXI-4130 Power SMU also includes a utility channel that can source either current or voltage with 16-bit setpoint and measurement resolution. You can use this output, which provides up to 6 V and 1 A, as a complementary power source to the SMU channel. Applications such as transistor characterization that require accurately sourcing a constant current or voltage while sweeping another current or voltage can greatly benefit from the reduced complexity, footprint, and cost that this module offers. For parallel test applications, you can use up to 17 PXI-4130 modules in a single PXI chassis for 17 SMU channels and 17 programmable power supply channels in a 19 in., 4U space.

Both channels of this PXI SMU can act as either a constant voltage source or a constant current source, with a settable compliance limit for either mode. In addition, you can enable remote sense on the SMU channel to maximize voltage output/measurement accuracy at your device under test for high-precision applications.
