Verify the connector type, channel pinout, remote-sense wiring, current rating and fixture configuration before ordering accessories.<\/p>\n<p>LabVIEW and InstrumentStudio are optional development and instrument-control products. The PXIe-4145 itself is supported through the NI-DCPower instrument driver.<\/p>\n<h3>What Is a Source Measure Unit?<\/h3>\n<p>A source measure unit combines precision sourcing and measurement functions in one instrument channel. It can source voltage while measuring current or source current while measuring voltage.<\/p>\n<p>This integrated architecture provides tighter control over the device-under-test operating point than using a separate power supply and digital multimeter. It also simplifies compliance control, four-quadrant operation and synchronized current-voltage measurements.<\/p>\n<p>The four PXIe-4145 channels allow several DUT pins or devices to be biased and measured simultaneously from one PXI module.<\/p>\n<h3>Four Independent SMU Channels<\/h3>\n<p>The PXIe-4145 provides four independently programmable SMU channels. Each channel can be assigned a different voltage, current limit, aperture time and measurement sequence.<\/p>\n<p>This channel density is useful for devices that require several power rails, bias voltages or monitored pins. Examples include application processors, power-management ICs, RF devices, microcontrollers, sensors and mixed-signal integrated circuits.<\/p>\n<p>Several PXIe-4145 modules can be installed in one PXI Express chassis when the test system requires more than four SMU channels.<\/p>\n<h3>\u00b16 V Voltage Range<\/h3>\n<p>Each PXIe-4145 channel can source and measure voltage from \u22126 V to +6 V. This range is designed for low-voltage electronic devices and modern semiconductor power rails.<\/p>\n<p>Typical applications include testing 1.2 V, 1.8 V, 2.5 V, 3.3 V and 5 V circuits. The bipolar range also allows negative bias voltages and reverse-polarity characterization within the module\u2019s operating limits.<\/p>\n<p>The connected device and test fixture must remain within the voltage, current and power boundaries of the selected channel configuration.<\/p>\n<h3>\u00b1500 mA DC Current Capability<\/h3>\n<p>Every SMU channel supports a DC current range from \u2212500 mA to +500 mA. Positive and negative current capability allows the channel to source current into a DUT or sink current from it.<\/p>\n<p>The maximum available current depends on the programmed voltage and the 3 W per-channel power boundary. The \u00b1500 mA rating therefore does not mean that every combination of \u00b16 V and \u00b1500 mA is available outside the specified operating area.<\/p>\n<p>Review the official quadrant and power-envelope diagrams when the application operates near the maximum voltage, current or power limits.<\/p>\n<h3>3 W Source and Sink Power<\/h3>\n<p>Each PXIe-4145 channel can source as much as 3 W of DC power and absorb as much as 3 W while operating within the specified four-quadrant boundaries.<\/p>\n<p>Sourcing power allows the SMU to energize the device under test. Sinking power allows it to absorb energy returned by the DUT, making the module useful for testing batteries, power-management circuits, regulators and bidirectional electronic devices at appropriate power levels.<\/p>\n<p>Power limits apply independently to each channel, but the complete module and chassis must also remain within their cooling and power-delivery requirements.<\/p>\n<h3>Four-Quadrant Operation<\/h3>\n<p>Four-quadrant operation means the PXIe-4145 can provide positive or negative voltage while sourcing or sinking current. This gives every channel the ability to operate as both a programmable source and an electronic load.<\/p>\n<table>\n<tbody>\n<tr>\n<th>Quadrant<\/th>\n<th>Voltage<\/th>\n<th>Current<\/th>\n<th>Typical Operation<\/th>\n<\/tr>\n<tr>\n<td>Quadrant I<\/td>\n<td>Positive<\/td>\n<td>Positive<\/td>\n<td>Sources power to a DUT<\/td>\n<\/tr>\n<tr>\n<td>Quadrant II<\/td>\n<td>Positive<\/td>\n<td>Negative<\/td>\n<td>Sinks current at positive voltage<\/td>\n<\/tr>\n<tr>\n<td>Quadrant III<\/td>\n<td>Negative<\/td>\n<td>Negative<\/td>\n<td>Sources power with negative polarity<\/td>\n<\/tr>\n<tr>\n<td>Quadrant IV<\/td>\n<td>Negative<\/td>\n<td>Positive<\/td>\n<td>Sinks current at negative voltage<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>This flexibility supports voltage sweeps, reverse-bias tests, leakage characterization and active discharge sequences without mechanically reversing the test connections.<\/p>\n<h3>15 pA Current Sensitivity<\/h3>\n<p>The PXIe-4145 provides current sensitivity down to 15 pA. This allows the module to detect small current changes while also supporting currents up to 500 mA.<\/p>\n<p>Low-current measurements require careful test-fixture design. Cable leakage, contamination, humidity, grounding and insufficient settling time can produce errors larger than the current being measured.<\/p>\n<p>Use clean connectors, short signal paths and suitable shielding when performing sensitive leakage-current tests.<\/p>\n<h3>Four-Wire Remote Sensing<\/h3>\n<p>Every PXIe-4145 channel supports four-wire remote sensing. Two conductors carry the source current, while two separate sense conductors measure the voltage directly at the DUT connection.<\/p>\n<p>Remote sensing compensates for voltage drop across test cables, connectors, relays and fixture wiring. It is particularly important when a channel supplies hundreds of milliamps through wiring with measurable resistance.<\/p>\n<p>The sense leads should connect close to the DUT terminals. Incorrect or open sense wiring can cause inaccurate output voltage or unstable channel behavior.<\/p>\n<h3>Local Sense vs Remote Sense<\/h3>\n<table>\n<tbody>\n<tr>\n<th>Sensing Method<\/th>\n<th>Connection<\/th>\n<th>Best Suited For<\/th>\n<\/tr>\n<tr>\n<td>Local Sense<\/td>\n<td>Voltage is regulated at the SMU output connector<\/td>\n<td>Short cables and lower-current applications<\/td>\n<\/tr>\n<tr>\n<td>Remote Sense<\/td>\n<td>Voltage is regulated at the DUT terminals<\/td>\n<td>Precision measurements and higher-current fixture paths<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Remote sensing improves voltage accuracy at the DUT, but it does not eliminate all fixture effects. Contact resistance, leakage, thermal effects and grounding must still be considered.<\/p>\n<h3>SourceAdapt Technology<\/h3>\n<p>SourceAdapt technology allows engineers to customize the transient response of each PXIe-4145 channel. The response can be adjusted to improve stability or reduce settling time for the connected load.<\/p>\n<p>A fixed SMU response may oscillate or settle slowly when connected to unusual capacitive, inductive or rapidly changing loads. SourceAdapt provides additional control over the source response so it can be matched more closely to the DUT and fixture.<\/p>\n<p>Start with a stable configuration and validate the resulting waveform before optimizing for speed. An overly aggressive response can increase overshoot or instability.<\/p>\n<h3>Fast Transient Measurements<\/h3>\n<p>The PXIe-4145 is designed for high-speed sampling and can capture transient current and voltage behavior that would be missed by a slower power supply and multimeter combination.<\/p>\n<p>Transient measurements can reveal device startup current, sleep-to-active transitions, regulator settling behavior and short-duration load changes.<\/p>\n<p>The effective measurement speed depends on the configured aperture, measurement range, sequence timing, source response and required accuracy.<\/p>\n<h3>Hardware-Timed Sequence Engine<\/h3>\n<p>The onboard sequence engine can execute programmed source and measurement steps without requiring a software command for every point. This reduces communication overhead and improves timing repeatability.<\/p>\n<p>A sequence can contain multiple voltage or current levels, compliance settings, source delays and measurements. Hardware execution is valuable for I-V sweeps, power-up profiles and repeated production tests.<\/p>\n<p>Sequence timing should allow the DUT and SMU output to settle before the associated measurement is recorded.<\/p>\n<h3>Synchronized Multichannel Operation<\/h3>\n<p>The PXIe-4145 channels can be synchronized with one another so several DUT power rails change state according to a defined timing relationship.<\/p>\n<p>The module can also coordinate with switches, digital instruments and other supported PXI devices. This enables complete test sequences containing power control, digital stimulus, signal routing and parametric measurements.<\/p>\n<p>Hardware triggers are preferable when repeatable timing is required across multiple instruments.<\/p>\n<h3>Voltage and Current Compliance<\/h3>\n<p>When sourcing voltage, the programmed current limit protects the DUT and defines the maximum current the channel may deliver. When sourcing current, the voltage limit defines the maximum voltage the SMU may apply.<\/p>\n<p>If the DUT attempts to draw current beyond the programmed limit, the channel enters compliance and the requested source value may no longer be maintained.<\/p>\n<p>Applications should record compliance status with the measurement result. A value collected while the channel is in compliance may not represent the intended DUT operating point.<\/p>\n<h3>I-V Characterization<\/h3>\n<p>The PXIe-4145 can sweep voltage while measuring current or sweep current while measuring voltage. The collected points form an I-V curve describing the electrical behavior of the device under test.<\/p>\n<p>Typical devices include diodes, LEDs, transistors, sensors, protection circuits and integrated-circuit pins. Hardware-timed sequencing reduces the time required to generate a large number of measurement points.<\/p>\n<p>Use suitable current compliance during voltage sweeps to protect the DUT from excessive current.<\/p>\n<h3>Power-Management IC Testing<\/h3>\n<p>Power-management integrated circuits often contain several inputs, outputs and control rails. Four SMU channels can independently power and monitor multiple PMIC pins.<\/p>\n<p>The PXIe-4145 can measure quiescent current, supply current, startup behavior, line regulation and load-dependent response. Four-quadrant operation also supports limited active-load functions within the channel power envelope.<\/p>\n<h3>Mobile Device and Processor Testing<\/h3>\n<p>Mobile processors, communication ICs and embedded controllers use multiple low-voltage power rails. The PXIe-4145 can apply these voltages and monitor current consumption during different operating states.<\/p>\n<p>Fast measurement capability helps characterize power transitions between sleep, idle and active modes. Synchronization with digital test hardware allows current measurements to be aligned with specific device operations.<\/p>\n<h3>LED and Optical Device Testing<\/h3>\n<p>The PXIe-4145 can source controlled current to LEDs and measure the resulting forward voltage. Multiple channels can test several devices or several sections of a multichannel optical component.<\/p>\n<p>Use appropriate current limits and thermal management. LED characteristics can change as the junction temperature rises during a measurement sequence.<\/p>\n<h3>Battery and Energy-Storage Testing<\/h3>\n<p>Four-quadrant operation allows the PXIe-4145 to source or sink current for low-power battery and energy-storage characterization within its \u00b16 V, \u00b1500 mA and 3 W limits.<\/p>\n<p>The module can perform controlled charge and discharge steps, measure terminal voltage and monitor current. It is not intended to replace a higher-power battery cycler when the device exceeds its voltage, current or energy-handling specifications.<\/p>\n<h3>Semiconductor Production Test<\/h3>\n<p>The four-channel design is well suited to production systems that require many precision source and measurement pins. Multiple PXIe-4145 modules can increase channel count while maintaining a compact PXI architecture.<\/p>\n<p>Hardware sequencing and synchronization help reduce test time. Fixture maintenance, contact verification and calibration control are also essential for consistent production measurements.<\/p>\n<h3>Typical PXIe-4145 Applications<\/h3>\n<ul>\n<li>Semiconductor parametric testing<\/li>\n<li>High-pin-count integrated-circuit testing<\/li>\n<li>Power-management IC validation<\/li>\n<li>Processor power-rail characterization<\/li>\n<li>Mobile device power testing<\/li>\n<li>I-V curve measurement<\/li>\n<li>Quiescent current measurement<\/li>\n<li>Leakage-current testing<\/li>\n<li>LED and photonic device testing<\/li>\n<li>Battery charge and discharge testing<\/li>\n<li>Sensor characterization<\/li>\n<li>Automated production testing<\/li>\n<li>Reliability and life testing<\/li>\n<li>Research laboratory automation<\/li>\n<\/ul>\n<h3>NI-DCPower Software Support<\/h3>\n<p>The PXIe-4145 is controlled through the NI-DCPower instrument driver. NI-DCPower provides functions for configuring source modes, output ranges, compliance limits, measurement timing, triggering and hardware sequences.<\/p>\n<p>The driver supports integration with LabVIEW, LabWindows\/CVI, C\/C++, .NET and other compatible programming environments.<\/p>\n<p>Use a driver version compatible with the PXI controller operating system and the firmware revision of the module.<\/p>\n<h3>InstrumentStudio Integration<\/h3>\n<p>InstrumentStudio provides an interactive interface for configuring PXIe-4145 channels, sourcing voltage or current, viewing measurements and validating a DUT connection before writing automated code.<\/p>\n<p>Engineers can use InstrumentStudio during system setup and troubleshooting. The automated production application can then use NI-DCPower to reproduce the validated configuration.<\/p>\n<h3>LabVIEW Integration<\/h3>\n<p>LabVIEW applications can configure all four SMU channels, execute hardware-timed sequences and coordinate the PXIe-4145 with other PXI instruments.<\/p>\n<p>Test applications can display real-time voltage and current measurements, generate I-V graphs, log results and monitor compliance conditions.<\/p>\n<h3>PXI Express System Integration<\/h3>\n<p>The PXIe-4145 installs in a compatible PXI Express chassis. It can operate alongside digital instruments, oscilloscopes, switching modules, waveform generators and RF devices.<\/p>\n<p>Before installation, verify chassis slot compatibility, available power and cooling. High-current multichannel operation can generate additional heat, so unobstructed chassis airflow is important.<\/p>\n<h3>Test-Fixture Design<\/h3>\n<p>A precision SMU system is only as accurate as its fixture and cabling. Use conductors sized for the expected current and separate remote-sense leads from force leads to the extent practical.<\/p>\n<p>Protect sensitive measurement paths from contamination and moisture. Consider guarding, shielding and low-leakage materials when measuring currents near the lower end of the module\u2019s range.<\/p>\n<p>External switching must be rated for the applied voltage, current and expected contact resistance.<\/p>\n<h3>PXIe-4145 Troubleshooting<\/h3>\n<h4>The PXIe-4145 is not detected<\/h4>\n<p>Confirm that the module is fully installed in a compatible PXI Express slot. Check chassis power, controller communication and NI-DCPower installation, then perform a self-test in NI Measurement &amp; Automation Explorer.<\/p>\n<h4>The output voltage is lower than programmed<\/h4>\n<p>Check whether the channel is in current compliance. Measure the DUT current and verify that the current limit is high enough for the expected load while remaining safe for the device.<\/p>\n<h4>The voltage at the DUT is inaccurate<\/h4>\n<p>Use four-wire remote sensing and connect the sense leads close to the DUT terminals. Inspect the force cable, relays, connectors and fixture contacts for excessive resistance.<\/p>\n<h4>The channel becomes unstable<\/h4>\n<p>Review the DUT capacitance, fixture inductance and cable length. Use SourceAdapt settings appropriate for the load and begin with a stable response configuration before attempting to reduce settling time.<\/p>\n<h4>The current reading is noisy<\/h4>\n<p>Increase the measurement aperture, select an appropriate current range and improve shielding and grounding. Check the fixture for leakage, contamination and unstable DUT behavior.<\/p>\n<h4>Low-current measurements are higher than expected<\/h4>\n<p>Disconnect the DUT and measure the fixture leakage. Clean the connectors and fixture surfaces, control humidity and use low-leakage materials for sensitive measurement paths.<\/p>\n<h4>The channel enters compliance during an I-V sweep<\/h4>\n<p>The DUT is requesting more current or voltage than the programmed limit permits. Review the sweep points, compliance settings and expected device behavior before increasing the limit.<\/p>\n<h4>Measurements are taken before the output settles<\/h4>\n<p>Increase the source delay or adjust the SourceAdapt response. Verify the transient waveform with an appropriate measurement instrument before shortening the delay.<\/p>\n<h4>One channel affects another channel<\/h4>\n<p>Inspect the DUT grounding, fixture wiring and shared return paths. Avoid allowing high-current return signals to create voltage drops in low-level measurement connections.<\/p>\n<h4>The module reports an overtemperature condition<\/h4>\n<p>Disable the outputs and allow the module to cool. Check chassis fan operation, airflow, ambient temperature and the source or sink power used by every channel.<\/p>\n<h3>PXIe-4145 Comparison with Related PXI SMUs<\/h3>\n<table>\n<tbody>\n<tr>\n<th>\u041c\u043e\u0434\u0435\u043b\u044c<\/th>\n<th>Primary Configuration<\/th>\n<th>Best Suited For<\/th>\n<\/tr>\n<tr>\n<td>PXIe-4145<\/td>\n<td>Four channels, \u00b16 V, \u00b1500 mA, 3 W per channel<\/td>\n<td>High-pin-count, low-voltage, higher-current device testing<\/td>\n<\/tr>\n<tr>\n<td>PXIe-4144<\/td>\n<td>Four-channel precision SMU architecture<\/td>\n<td>Related low-voltage multichannel SMU applications<\/td>\n<\/tr>\n<tr>\n<td>PXIe-4143<\/td>\n<td>Four-channel SMU with a wider voltage range<\/td>\n<td>Multichannel devices requiring higher voltage and lower current<\/td>\n<\/tr>\n<tr>\n<td>PXIe-4139<\/td>\n<td>Single-channel high-precision system SMU<\/td>\n<td>Research and characterization requiring wider operating capability<\/td>\n<\/tr>\n<tr>\n<td>PXIe-4163<\/td>\n<td>High-density multichannel SMU<\/td>\n<td>Applications prioritizing maximum pin count<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h3>PXIe-4145 vs PXIe-4143<\/h3>\n<p>The PXIe-4145 is optimized for lower-voltage devices that require current up to 500 mA.
