The NI PXI-4130 combines an isolated four-quadrant SMU channel with a separate utility output. Channel 1 supports up to ±20 V at 2 A when used with the APS-4100 auxiliary power supply.

Key product information and technical features.
The PXI-4130 supports programmable source-and-measure operations through NI-DCPower. Voltage or current updates can be combined with measurements in software-controlled loops for device testing and characterization.
Power configuration matters: operation without auxiliary power restricts channel 1 to a 2 W/300 mA operating envelope. Select the power arrangement before evaluating the required voltage-current operating points.

Product-specific answers based on available technical information.
No. NI states that PXI-4130 sequences and sweeps must be performed and timed by software. Output settling and measurement averaging affect the achievable source-measure loop rate.
NI documents series and parallel configurations for channel 1 using APS-4100 auxiliary supplies. Follow the documented wiring, isolation limits, and stability checks; parallel voltage-mode operation requires particular care to prevent one SMU from sinking another's output.
