It has a single isolated SMU channel that offers a four-quadrant ±20 V 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 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 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. 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. 200 mA Maximum Power Quadrants I and III = 40 W Quadrants II and IV = 10 W 20 mA Quadrant II Sink 2 mA Quadrant I Source 200 µA -20 V 20 V -200 µA Quadrant III Source -2 mA -20 mA Quadrant IV Sink -200 mA -2 A Figure 1. Channel 1 Quadrant Diagram (40 W in Quadrants I and III, 10 W in Quadrants II and IV) 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 V channel can be operated at its full 1 A current range, but the isolated SMU channel is limited to 300 mA or 2 W. When externally powered, the SMU channel can source up to 2 A at 20 V in addition to the utility channel, which sources up to 1 A at 6 V for a total maximum output power of 46 W. 20 V, 2 A Source Measure Unit Software for Programmatic Control NI-DCPower, an IVI-compliant instrument driver, offers complete programmatic control of the PXI-4130. You can use the NI-DCPower soft front panel to quickly troubleshoot or debug power supply operation. You can take advantage of the DCPower Express VI for an intuitive, configuration-based method of programming in the NI LabVIEW graphical development environment or the LabVIEW SignalExpress programming-free environment. For low-level control of SMU hardware, the NI-DCPower instrument driver provides a complete API that exposes the full functionality of the hardware in an intuitive hierarchy. NI-DCPower also includes example programs that demonstrate concepts ranging from simple configuration to advanced sweeping and monitoring. Extensive Protection Features In addition to standard voltage and current limiting functionality, the PXI-4130 offers several other features to protect the supply and the load. The nonisolated output is protected against a reverse-polarity voltage application, and both outputs are protected against excessive voltages. Output fuses provide additional protection to prevent catastrophic failure as a last line of defense. The operating voltage range for the auxiliary power input is 11 to 15.5 V. If the PXI-4130 detects voltages outside these limits, it shuts down until an input voltage within range is applied. If an input larger than 20 V is applied, the input crowbar protection turns on, protecting the input solid-state switching devices (and preregulator power supply) from overvoltage damage. The PXI-4130 operates with only nominal temperature increases internally due to the intelligent digital power control of the output devices. If an overtemperature condition occurs in the PXI chassis due to fan failure or intake blockage, the output channels are shut down and a warning is issued. This type of condition requires user software intervention to reset, thus preventing the module from damage at excessive temperatures.

Figure 2 shows the connections for performing IV curve tracing on a MOSFET using the PXI-4130. In this configuration, the utility channel is used to set a constant value for the gate-source voltage and the SMU channel is used to sweep the drain-source voltage and measure the induced current. You can also configure remote-sense connections on the SMU channel to precisely measure the drain-source voltage so that the IV curve data is as accurate as possible.

Connections for Performing IV Curve Tracing on a MOSFET Using the PXI-4130 Battery Charge-Cycle Testing and Rechargeable Source Simulation The SMU channel on the PXI-4130 has the ability to sink up to 10 W of power, making it ideal for charge-cycle testing on rechargeable batteries. The configuration shown on the left side of Figure 3 illustrates the connections needed to charge and discharge a battery in either constant current or constant voltage mode. The remote-sense terminals precisely measure the voltage directly at the battery. Alternatively, you can use the PXI-4130 as a source simulator to test chargers or power other electronic devices. For rechargeable source simulation, replace the battery in Figure 3 with a charger or other device under test.
