This channel is capable of sourcing and sinking up to 2 W Item A B OUTPUT STATUS 100 V V+ 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 –50 mA Quadrant III Source Quadrant IV Sink organic LEDs using the onboard hardware sequencing engine. In addition, you can synchronize multiple PXI-4132 SMUs via the PXI backplane to provide highspeed 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 –100 mA I– Figure 1. PXI-4132 Quadrant Diagram for 17 high-precision SMU channels in a 19 in., 4U space. 100 V Precision Source Measure Unit (SMU) For power requirements higher than 2 W, consider the NI PXI-4130 power Sequence Loop Count 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 Start Sequence Trigger Advance Trigger* 10 µA, each of which offers superior measurement sensitivity to traditional “Sequence” Num Steps “Step” Source Trigger Source Source Measure Delay SMUs, thereby allowing for more precise readings over a wider range. You can configure the programmable aperture time to optimize both measurement speed Source Complete Event 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, Measure Complete Event Sequence Sequence Iteration Engine Complete Done Event Event 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 Figure 4. Sequence Engine Diagram 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.

Noise versus Aperture Time (typical) 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.
