Overview
The NI PXI-4132 is a programmable, high-precision source measure unit (SMU)
in a single-slot, 3U PXI module. It has a single, isolated SMU channel that offers
a four-quadrant, ±100 V output incorporating remote (4-wire) sense as well as
external guarding. This channel is capable of sourcing and sinking up to 2 W
maximum – as shown in Figure 1, it can operate at up to 100 V at up to 20 mA,
up to 40 V at up to 50 mA, and up to 20 V at up to 100 mA.

With measurement resolution down to 10 pA and integrated guarding, the
PXI-4132 precision source is ideal for high-accuracy leakage measurements on
integrated circuits, discrete components, PCBs, and cables. You can also perform
high-speed I-V measurements on a variety of components including diodes and

organic LEDs using the onboard hardware sequencing engine. In addition, you
can synchronize multiple PXI-4132 SMUs via the PXI backplane to provide high-
speed I-V measurements on transistors and more complex devices. For parallel
test applications, you can use up to 17 PXI-4132 modules in a single PXI chassis

For power requirements higher than 2 W, consider the NI PXI-4130 power
SMU, which offers up to 40 W (±20 V at up to ±2 A) and an additional power
supply channel that can source up to 6 V at 1 A.

Analog Performance
The PXI-4132 features five selectable current ranges, from 100 mA down to
10 µA, each of which offers superior measurement sensitivity to traditional
SMUs, thereby allowing for more precise readings over a wider range. You can
configure the programmable aperture time to optimize both measurement speed
and quality for your application. Figure 3 shows a graph of typical measurement
noise as a function of aperture time for any given range. For instance, at 1 PLC,
current measurements have a sensitivity of roughly 1 ppm of the range – for
the 10 µA range, this corresponds to 10 pA. The PXI-4132 was designed to
optimize sensitivity at a variety of measurement rates (PLC settings). For
instance, on the 10 µA current measurement range, you can typically achieve
100 pA sensitivity at up to 1000 readings per second.

Hardware Control
You can use the NI-DCPower software test panel to quickly troubleshoot
or debug SMU operation interactively. For fast programming, you can take
advantage of the DCPower Express VI for an intuitive, configuration-based
method of controlling NI SMUs in the NI LabVIEW graphical development
environment. For low-level control of the SMU hardware, the IVI-compliant
NI-DCPower instrument driver provides a complete API that exposes the full
functionality of the hardware in an intuitive hierarchy. NI-DCPower also includes
prewritten example programs that demonstrate concepts ranging from simple
configuration to advanced sweeping and monitoring.
The new PXI-4132 features a high-speed sequencing engine that you can use
to synchronize multiple PXI-4132 SMUs or to synchronize to a single PXI-4132
with other instruments such as switches and high-speed digital devices. As
shown in Figure 4, you can send and receive events and triggers across the
PXI backplane, simplifying both programming and system wiring. Using this
capability, you can easily perform accurate current and voltage sweeps for
high-speed I-V characterization.

System Assurance Programs
NI system assurance programs are designed to make it even easier for you
to own an NI system. These programs include configuration and deployment
services for your NI PXI, CompactRIO, or Compact FieldPoint system. The NI Basic
System Assurance Program provides a simple integration test and ensures that
your system is delivered completely assembled in one box. When you configure
your system with the NI Standard System Assurance Program, you can select
from available NI system driver sets and application development environments
to create customized, reorderable software configurations. Your system arrives
fully assembled and tested in one box with your software preinstalled. When
you order your system with the standard program, you also receive system-
specific documentation including a bill of materials, an integration test report,
a recommended maintenance plan, and frequently asked question documents.
Finally, the standard program reduces the total cost of owning an NI system
by providing three years of warranty coverage and calibration service. Use the
online product advisors at
ni.com/advisor
to find a system assurance program
to meet your needs.
