Each channel can source voltage or current, apply compliance limits and measure the resulting voltage and current.<\/p>\n<p>This integration can replace several standalone power supplies, electronic loads and digital multimeters in compact automated test systems.<\/p>\n<h3>Four-Quadrant Operation<\/h3>\n<p>Each channel can source or sink positive and negative voltage and current. This four-quadrant capability allows the PXIe-4141 to power devices, generate I-V sweeps and absorb limited returned power.<\/p>\n<p>The module can operate as a precision voltage source, current source or limited electronic load within its specified voltage, current and power envelope.<\/p>\n<h3>\u00b110 V and \u00b1100 mA Capability<\/h3>\n<p>Every channel supports voltage from -10 V to +10 V and current up to \u00b1100 mA. Maximum DC source and sink power is 1 W per channel.<\/p>\n<p>The selected voltage and current combination must remain within the 1 W channel power limit. Maximum voltage and maximum current cannot necessarily be applied simultaneously.<\/p>\n<h3>Multiple Current Ranges<\/h3>\n<p>Available current ranges include 10 \u00b5A, 100 \u00b5A, 1 mA, 10 mA and 100 mA. These ranges allow the same channel to measure low leakage currents and higher device operating currents.<\/p>\n<p>Selecting the smallest range that safely covers the expected current generally provides the best resolution and accuracy.<\/p>\n<h3>10 pA Current Sensitivity<\/h3>\n<p>On the 10 \u00b5A range, the PXIe-4141 provides resolution and noise down to 10 pA under specified conditions. This makes it suitable for leakage-current testing, standby-current measurements and precision semiconductor characterization.<\/p>\n<p>Low-current performance also depends on fixture cleanliness, guarding, insulation resistance, shielding, aperture time and environmental stability.<\/p>\n<h3>600 kS\/s Measurement Rate<\/h3>\n<p>The PXIe-4141 can continuously transfer voltage and current measurements to the host at up to 600 kS\/s per channel. This enables detailed capture of device startup behavior, transient currents and rapid changes in operating state.<\/p>\n<p>The effective sampling rate depends on the selected aperture, source delay, sequence configuration and DUT settling time.<\/p>\n<h3>High-Speed Source Sequencing<\/h3>\n<p>The module supports source updates up to 100 kS\/s per channel for compatible sequences containing fewer than 300 steps per iteration. Longer sequences support up to 100 kS\/s per board.<\/p>\n<p>Hardware sequencing reduces communication overhead by allowing the SMU to execute voltage and current changes without requiring a separate host command for every test point.<\/p>\n<h3>Four-Wire Remote Sensing<\/h3>\n<p>Each channel includes four-wire remote sensing to compensate for voltage lost across power cables, switches and test fixtures. The sense conductors measure voltage directly at the DUT without carrying the primary load current.<\/p>\n<p>The PXIe-4141 supports up to 1 V of lead drop per remote-sense lead under the specified operating conditions.<\/p>\n<h3>NI SourceAdapt Technology<\/h3>\n<p>NI SourceAdapt uses a programmable digital control loop to customize the transient response of each SMU channel. Engineers can select slow, normal or fast modes or configure a custom response for the connected load.<\/p>\n<p>Custom tuning can reduce overshoot, oscillation and settling time when testing capacitive, inductive or dynamically changing devices.<\/p>\n<h3>Programmable Output Resistance<\/h3>\n<p>The PXIe-4141 supports programmable output resistance over a range that depends on the selected current limit. This functionality can be used to simulate nonideal voltage sources, batteries or power rails with defined series resistance.<\/p>\n<p>Programmable resistance is also useful for evaluating how a DUT responds to changes in source impedance without adding external resistors to the test fixture.<\/p>\n<h3>Shared Common LO Configuration<\/h3>\n<p>The four channels are isolated from earth ground but share a common LO reference. The channels are therefore not independently isolated from one another.<\/p>\n<p>Verify that all connected DUT rails can safely share the same low reference. Conflicting ground potentials may cause measurement errors or unintended current paths.<\/p>\n<h3>Hardware Timing and Triggering<\/h3>\n<p>The PXIe-4141 supports start, source, sequence-advance and measurement triggers through PXI trigger lines. It can also export source-complete, measure-complete and sequence-completion events.<\/p>\n<p>This allows deterministic synchronization with switches, digital pattern instruments, digitizers and other PXI source measure units.<\/p>\n<h3>\u0422\u0438\u043f\u0438\u0447\u043d\u044b\u0435 \u043f\u0440\u0438\u043c\u0435\u043d\u0435\u043d\u0438\u044f<\/h3>\n<ul>\n<li>Semiconductor component characterization<\/li>\n<li>Mixed-signal IC production testing<\/li>\n<li>Power management IC testing<\/li>\n<li>MEMS and sensor testing<\/li>\n<li>Leakage-current measurement<\/li>\n<li>Standby-current testing<\/li>\n<li>Rapid I-V curve generation<\/li>\n<li>Multirail power sequencing<\/li>\n<li>Battery-powered device simulation<\/li>\n<li>High-pin-count automated validation<\/li>\n<\/ul>\n<h3>Software Compatibility<\/h3>\n<p>The PXIe-4141 is controlled using the NI-DCPower instrument driver. NI-DCPower provides APIs for voltage and current sourcing, measurements, compliance limits, remote sensing, programmable resistance, SourceAdapt, triggering and sequencing.<\/p>\n<p>InstrumentStudio can be used for interactive configuration and measurements. Automated systems can be developed using LabVIEW, LabWindows\/CVI, supported .NET environments and NI TestStand.<\/p>\n<h3>PXI Express System Integration<\/h3>\n<p>The PXIe-4141 occupies one 3U PXI Express or compatible CompactPCI Express slot. It receives operating power from the PXI chassis and does not require a separate auxiliary power supply.<\/p>\n<p>Verify chassis power, cooling, controller compatibility and available slot type before installation. When the chassis provides adjustable fan speeds, use the setting required by the official specifications.<\/p>\n<h3>PXIe-4141 Connection Guidance<\/h3>\n<ul>\n<li>Power off the chassis before installing or removing the module.<\/li>\n<li>Use the supplied terminal block and pinout overlay.<\/li>\n<li>Confirm the shared common LO configuration before wiring the DUT.<\/li>\n<li>Set safe voltage and current compliance limits.<\/li>\n<li>Use remote sensing to compensate for connection resistance.<\/li>\n<li>Apply guarding techniques for low-current measurements.<\/li>\n<li>Allow at least 30 minutes of warm-up for precision testing.<\/li>\n<li>Perform self-calibration according to the measurement requirements.<\/li>\n<\/ul>\n<h3>PXIe-4141 Troubleshooting<\/h3>\n<h4>A channel enters compliance unexpectedly<\/h4>\n<p>Check the programmed voltage or current limit, DUT impedance and fixture wiring. Excessive connection resistance or incorrect sense wiring may also cause compliance operation.<\/p>\n<h4>The DUT voltage differs from the programmed voltage<\/h4>\n<p>Enable four-wire remote sensing and connect the sense terminals directly to the DUT. Confirm that lead voltage drop remains within the supported range.<\/p>\n<h4>Low-current readings are unstable<\/h4>\n<p>Use the smallest suitable current range, increase the aperture time and inspect the test fixture for contamination or leakage. Use guard connections and shield sensitive wiring.<\/p>\n<h4>The output oscillates with the connected load<\/h4>\n<p>Select a slower SourceAdapt mode or customize the control-loop response for the load. Capacitive and inductive DUTs may require different transient settings.<\/p>\n<h4>Multiple channels influence one another<\/h4>\n<p>The four channels share a common LO. Check for incompatible floating references, unintended grounding or incorrect fixture connections.<\/p>\n<h4>The module reports a thermal or protection error<\/h4>\n<p>Verify chassis airflow and fan operation. Reduce simultaneous channel power and confirm that all voltage, current and power limits are observed.<\/p>\n<h3>PXIe-4141 Compared with Related SMUs<\/h3>\n<table>\n<thead>\n<tr>\n<th>\u041c\u043e\u0434\u0435\u043b\u044c<\/th>\n<th>\u041a\u0430\u043d\u0430\u043b\u044b<\/th>\n<th>Voltage Range<\/th>\n<th>\u041c\u0430\u043a\u0441\u0438\u043c\u0430\u043b\u044c\u043d\u044b\u0439 \u0442\u043e\u043a<\/th>\n<th>Current Sensitivity<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>PXIe-4141<\/td>\n<td>4<\/td>\n<td>\u00b110 V<\/td>\n<td>\u00b1100 mA<\/td>\n<td>10 pA<\/td>\n<\/tr>\n<tr>\n<td>PXIe-4143<\/td>\n<td>4<\/td>\n<td>\u00b124 V<\/td>\n<td>\u00b1150 mA<\/td>\n<td>10 pA<\/td>\n<\/tr>\n<tr>\n<td>PXIe-4145<\/td>\n<td>4<\/td>\n<td>\u00b16 V<\/td>\n<td>\u00b1500 mA<\/td>\n<td>15 pA<\/td>\n<\/tr>\n<tr>\n<td>PXIe-4142<\/td>\n<td>4<\/td>\n<td>\u00b124 V<\/td>\n<td>\u00b1150 mA<\/td>\n<td>100 pA<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h3>Recommended Related Products<\/h3>\n<ul>\n<li><a href=\"https:\/\/pxisource.com\/ru\/product\/pxie-4143\/\">NI PXIe-4143 Precision Source Measure Unit<\/a> \u2013 Provides four \u00b124 V, \u00b1150 mA channels for applications requiring a wider voltage range.<\/li>\n<li><a href=\"https:\/\/pxisource.com\/ru\/product\/pxie-4145\/\">NI PXIe-4145 Precision Source Measure Unit<\/a> \u2013 Offers four \u00b16 V channels with current up to \u00b1500 mA.<\/li>\n<li><a href=\"https:\/\/pxisource.com\/ru\/product\/pxie-4142\/\">NI PXIe-4142 Source Measure Unit<\/a> \u2013 A \u00b124 V, \u00b1150 mA alternative without custom SourceAdapt tuning.<\/li>\n<li><a href=\"https:\/\/pxisource.com\/ru\/product\/%d0%bf%d0%ba%d1%81%d0%b8%d0%b5-6571\/\">NI PXIe-6571 Digital Pattern Instrument<\/a> \u2013 Can be synchronized with PXI SMUs for mixed-signal semiconductor production testing.<\/li>\n<\/ul>\n<h3>How to Select the Correct PXI SMU<\/h3>\n<p>Choose the PXIe-4141 when the application requires four precision \u00b110 V channels, up to \u00b1100 mA and current sensitivity down to 10 pA.
