Four-Quadrant Source and Measurement Operation
The PXIe-4137 can operate as both a source and an electronic load. It can source positive or negative voltage and source or sink current, providing four-quadrant operation for detailed current-voltage characterization.
This functionality allows the module to simulate batteries, power supplies and active loads while simultaneously measuring the electrical response of the device under test.
100 fA Low-Current Measurement Sensitivity
With current sensitivity down to 100 fA, the PXIe-4137 can measure very small leakage, standby and quiescent currents. This capability is useful when characterizing semiconductor devices that operate across a wide dynamic current range.
For the best low-current performance, use proper shielding, guarding, clean connectors, suitable cabling and an appropriate measurement aperture. Environmental noise, fixture contamination and cable leakage can affect femtoamp-level measurements.
±200 V and High-Power Output Capability
The ±200 V output range supports high-voltage semiconductor components, optical devices, protection devices and board-level circuits. The module can continuously source or measure up to ±1 A and generate pulsed currents up to ±3 A within its supported operating envelope.
Part number 783761-02 provides up to 40 W of continuous DC source and sink power. The extended pulsed operating region supports short-duration device tests requiring substantially higher instantaneous power.
High-Speed Measurements and Sequencing
The PXIe-4137 supports high-speed acquisitions at rates up to 1.8 MS/s. This allows engineers to capture transient current consumption, power-up behavior, pulsed device response and other dynamic characteristics that conventional precision measurements may miss.
Its hardware-timed sequencing engine can execute voltage or current sweeps without continuous software intervention. Multiple SMUs and other PXI instruments can be synchronized through PXI Express timing and trigger resources.
NI SourceAdapt Technology
SourceAdapt technology allows engineers to customize the PXIe-4137 control-loop response for the electrical characteristics of the DUT, test fixture and cabling.
Adjusting transient response can improve settling time and stability when testing capacitive, inductive or rapidly changing loads. This is particularly valuable for semiconductor devices whose load characteristics vary significantly between operating states.
Four-Wire Remote Sensing
Four-wire remote sensing compensates for voltage drops across output cables and fixture connections. Separate sense connections measure voltage directly at the DUT, allowing the SMU to regulate the programmed voltage more accurately at the test point.
Remote sensing is recommended for higher-current measurements, long test cables and applications where connection resistance could materially affect voltage accuracy.

Software and Driver Support
The PXIe-4137 is controlled using the NI-DCPower instrument driver. Engineers can configure voltage and current source modes, output limits, measurement apertures, source delays, triggering, sequencing and SourceAdapt settings.
Compatible software environments include NI LabVIEW, InstrumentStudio, TestStand, LabWindows/CVI, C/C++, .NET and supported Python workflows. Verify driver, operating-system and application-software compatibility before integrating the module into an existing PXI system.
PXI Chassis and System Integration
The PXIe-4137 occupies one PXI Express peripheral slot and requires a compatible PXI Express chassis and controller. The chassis must provide sufficient slot power and cooling for the selected power configuration.
System planning should also include the correct connector kit, backshell, high-voltage wiring, test fixture, interlocks and DUT protection. Review voltage, current, power and environmental limits before operating the module.
PXIe-4137 Troubleshooting
Why does the PXIe-4137 enter compliance?
The DUT may be drawing more current or voltage than the programmed limit allows. Confirm the compliance settings, selected range, wiring and expected DUT behavior before increasing a limit.
Why are low-current measurements unstable?
Use guarded and shielded connections, clean the fixture and connectors, increase the measurement aperture and reduce nearby electrical interference. Cable leakage and contaminated insulation can significantly affect femtoamp-level measurements.
Why does the output oscillate or settle slowly?
The default source response may not be optimized for the DUT capacitance, inductance or test-cable characteristics. Adjust the SourceAdapt settings to improve stability and settling performance.
Why is the voltage at the DUT lower than the programmed value?
Check whether the SMU is operating in current compliance and inspect the resistance of the output wiring. Use four-wire remote sensing to compensate for voltage drops between the module and DUT.
Why is the full output power unavailable?
Verify the PXIe-4137 part number, chassis cooling, operating region and configured voltage-current combination. The 783761-01 and 783761-02 versions have different continuous source and sink power ratings.
