Built for Automated Test and Measurement
NI’s source measure units (SMUs) are optimized for building automated test systems, with hardware features to reduce test execution time and tight software integration to reduce development effort. Built on the modular PXI platform, NI SMUs can be combined with other instruments such as oscilloscopes, RF generators and analyzers, and digital instruments to build mixed-signal test systems with multi-core processors and low latency communication. Additionally, the modularity and channel density of these instruments allow you to build systems that test multiple devices in parallel and improve the throughput of each tester.
NI system SMUs combine power, precision, and speed into a single instrument. The combination of power and precision allows you to use the same instrument for both high-power sweeps and low-current measurements, while the addition of a high-speed update rate and sampling rate allows you to use the instrument in non-traditional ways, such as generating and measuring a waveform. These modules also include traditional SMU features such as output disconnect relays to isolate the instrument from your circuit, remote sense to compensate for lead drop, and guard to minimize leakage current in small signals. This combination of features allows you to use NI system SMUs in a wide range of applications, from materials research and parametric test to high volume production test of RF and mixed-signal ICs.

Key Features

Channel Density and Scalability
SMU channel density is increasingly important for multi-site testing and for improving test throughput in applications like reliability that require inherently long stress and measurement cycles. The modularity of the PXI platform allows you to optimize the size of your test system and number of parallel SMU channels by choosing the appropriate chassis and instruments. In a single PXI chassis, you can add up to 17 system SMU channels, mix with higher density SMUs or switches, or combine with other types of instruments to build tightly integrated mixed signal test systems. For even larger systems, you can mount multiple chassis in an automated test rack and combine them together with chassis expansion cards.

Figure 1: You can add up to 17 system SMU channels in a single 4U, 19-inch PXI chassis.

Hardware-Timed Sequencing and Triggering
NI SMUs have a hardware-timed, deterministic sequencing engine that allows the instrument to execute commands and acquire data without any intervention from the host software. This eliminates the software overhead and jitter associated with software controlled sequences, and reduces the execution time of your overall test. Within these hardware-timed sequences, you can modify over 30 properties such as aperture time, current range, voltage range, DC output mode, and source delay, to optimize each step within your sequence. Additionally, the timing engine gives you the flexibility to repeat a sequence for a finite number of steps, or continuously source and measure for an infinite amount of time.
Each SMU has numerous triggers and events such as source trigger, measure trigger, and measure complete, that you can share via the backplane of the PXI chassis to communicate between different instruments. This allows you to synchronize the start of multiple SMUs, create nested sweeps, or send/receive commands from other instruments like oscilloscopes and RF analyzers.

High-Speed Measurement and Update Rate
NI system SMUs can sample up to 1.8 MS/s and source up to 100 kS/s, which adds new functionality to a traditionally DC instrument. The high speed sampling rate allows you to use the SMU as a high voltage or current digitizer to capture transient behavior or monitor current consumption over time. The fast update rate allows you to step through large sequences very quickly or use the SMU to generate arbitrary waveforms at low frequencies. Since NI SMUs communicate and share data via a high bandwidth, low latency PCI express interface, you can use the full update and sampling rate of the instrument to stream data to and from the host PC. This functionality is transparent to the user and does not require you to configure a buffer, allocate memory, or pause your acquisition and wait for data to transfer from the instrument to the host.

High-Precision, High-Accuracy Measurements
NI SMUs are built with a combination of off-the-shelf high-speed ADC technology and a custom-designed sigma-delta converter to provide low noise measurements across a wide range of measurement speeds. This design results in a high dynamic measurement range that allows you to measure small changes in a signal without constantly changing ranges. It also allows you to optimize your measurement cycle based on your test requirements, so you can adjust the instrument’s aperture time based on the acceptable level of noise for a test.
NI SMUs include a built-in self-calibration feature that corrects for time and temperature drift by recalculating certain internal reference values, gains, and offsets. This method significantly improves accuracy over the full operating temperature range of the device by reducing sources of error such as gain and offset error for voltage and current. For high accuracy devices with +/- 1 deg C specifications, the self-calibration routine helps ensure your device is operating within 1 degree of its calibrated temperature and that you can apply the tighter accuracy specifications. The self-calibration routine takes less than 10 seconds to complete and can be called programmatically from your application software.

SourceAdapt Digital Control Loop Technology
SourceAdapt is a digital control loop technology that gives you the ability to optimize the SMU response for any device under test (DUT). This provides fast and stable measurements for a variety of loads, even highly capacitive or inductive loads, and prevents damage to your DUT by removing harmful overshoots and oscillations. By allowing complete customization of the SMU response, this technology allows you to remove unwanted characteristics of the instrument while still maintaining a fast settling time – all without adding any custom circuitry between the instrument and the load. Because this capability is handled programmatically, you can quickly reconfigure your SMU for high speed or high stability testing and maximize the usage of your instrument.

Figure 2. SourceAdapt gives you the ability to optimize the SMU response for any DUT.

Extended Range Pulsing
Certain NI system SMUs are capable of exceeding their 20 W DC power boundary and generating pulses up to 500 W. Generating short, high-power pulses allows you to test devices such as high-brightness LEDs and power transistors while minimizing heat dissipation in the DUT. Having a single device capable of sourcing or sinking up to 500 W reduces the need for stacking multiple SMUs in parallel, and generating short, accurate pulses reduces the need for thermal management systems.

NI-DCPOWER Application Programming Interface (API)

In addition to the soft front panel, the NI-DCPower driver includes a best-in- class API that works with a variety of development options such as LabVIEW, C/C++, C#, and others. To ensure long-term interoperability of SMUs and power supplies, the NI-DCPower driver API is the same API used for all past and current NI SMUs and power supplies. The driver also provides access to help files, documentation, and dozens of ready-to-run shipping examples you can use as a starting point for your application.

NI-DCPOWER Soft Front Panel

The NI-DCPower driver software includes an interactive soft front panel for full out-of-the-box functionality. This interactive soft front panel includes two modes: one for constantly outputting a DC current or voltage, and another for performing one or two channel sweeps. In addition, you can enable a Debug Driver Session to monitor and debug the instrument during automated measurements.

Platform-Based Approach to Test and Measurement

What Is PXI?
Powered by software, PXI is a rugged PC-based platform for measurement and automation systems. PXI combines PCI electrical-bus features with the modular, Eurocard packaging of CompactPCI and then adds specialized synchronization buses and key software features. PXI is both a high-performance and low-cost deployment platform for applications such as manufacturing test, military and aerospace, machine monitoring, automotive, and industrial test. Developed in 1997 and launched in 1998, PXI is an open industry standard governed by the PXI Systems Alliance (PXISA), a group of more than 70 companies chartered to promote the PXI standard, ensure interoperability, and maintain the PXI specification.

Integrating the Latest Commercial Technology
By leveraging the latest commercial technology for our products, we can continually deliver high-performance and high-quality products to our users at a competitive price. The latest PCI Express Gen 3 switches deliver higher data throughput, the latest Intel multicore processors facilitate faster and more efficient parallel (multisite) testing, the latest FPGAs from Xilinx help to push signal processing algorithms to the edge to accelerate measurements, and the latest data converters from TI and ADI continually increase the measurement range and performance of our instrumentation.

PXI Instrumentation
NI offers more than 600 different PXI modules ranging from DC to mmWave. Because PXI is an open industry standard, nearly 1,500 products are available from more than 70 different instrument vendors. With standard processing and control functions designated to a controller, PXI instruments need to contain only the actual instrumentation circuitry, which provides effective performance in a small footprint. Combined with a chassis and controller, PXI systems feature high-throughput data movement using PCI Express bus interfaces and sub-nanosecond synchronization with integrated timing and triggering.
