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 17 high-precision SMU channels in a 19 in., 4U space.
