The NI PXI-4130 is a programmable, high-power source measure unit
(SMU) in a single-slot, 3U PXI module. It has a single isolated SMU
channel that offers a four-quadrant ±±0 ꢀ output that incorporates
remote (4-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 Iꢀ. 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 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 ꢀ 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.
Both channels of the PXI-4130 power 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.

Internal/External Supply Options
You can power the PXI-4130 either internally from the PXI backplane or
externally through a front-panel-connected auxiliary DC supply such as
the NI APS-4100. When internally powered, the ground-referenced, 0 to
6 ꢀ channel can be operated at its full 1 A current range, but the isolated
SMU channel is limited to 300 mA or ± W. When externally powered,
the SMU channel can source up to ± A at ±0 ꢀ in addition to the utility
channel, which sources up to 1 A at 6 ꢀ for a total maximum output
power of 46 W.
