When working with PXI Modules for electronic testing, you often need a precise, high-performance power supply. One of the popular solutions is the NI PXIe-4143 module. But what exactly is it, and where can you use it? Let’s break it down in simple words.
What is the NI PXIe-4143?
The NI PXIe-4143 is a source measure unit (SMU). Simply put, it’s a device that can both provide voltage/current and measure the response of the device being tested at the same time. The PXIe-4143 is part of the PXI Modules family developed by National Instruments (NI), designed to fit into PXI Express (PXIe) systems.
Here are some basic specs of the PXIe-4143:
-
Voltage range: ±20 V
-
Current range: ±100 mA
-
Sampling speed: Up to 600,000 samples per second
-
Four-quadrant operation: It can both source and sink voltage/current.
In short, this module gives engineers precise control over power during testing while collecting detailed measurement data at high speeds.
Main Features of the PXIe-4143 Module
When compared to other PXI Modules, the PXIe-4143 stands out because of its balance between precision and speed. Here are some of its key features:
-
High accuracy: Ideal for sensitive devices like sensors, ICs, or battery cells.
-
Fast dynamic response: Quickly adapts to sudden changes in load.
-
Seamless integration with LabVIEW: Easy to automate tests and data collection.
-
Parallel testing: You can run multiple PXIe-4143 modules in one chassis to test several devices at the same time.
Thanks to its compact PXI Express form factor, the PXIe-4143 saves space while offering professional-grade performance.
Where Can You Use the NI PXIe-4143?
The NI PXIe-4143 module is perfect for situations where you need precise power control and measurement. Here are some common use cases:
Semiconductor Testing
Engineers use the PXIe-4143 to supply and measure voltage and current during semiconductor validation. This helps to verify chip performance under different power conditions.
Battery Simulation
The PXIe-4143 can simulate small batteries or power sources. This is very useful when testing battery-powered devices without relying on real batteries.
IoT Device Validation
Since many IoT devices consume very low power, you need a sensitive module like the PXIe-4143 to accurately test their energy consumption, wake-up times, and charging behavior.
Research and Development
In R&D labs, the PXIe-4143 supports prototyping and debugging new electronic designs that require detailed electrical measurements.
Why Choose the PXIe-4143 Over Other PXI Modules?
There are many PXI Modules out there, but the NI PXIe-4143 is a great choice when you need:
-
Precise low-level current measurements
-
High sampling speed
-
Flexibility to both source and sink current
-
Tight integration with PXI test systems and software like LabVIEW or TestStand
While there are other source measure units in the PXI Modules line-up, the PXIe-4143 is particularly well-suited for applications where speed, sensitivity, and accuracy are critical.
The NI PXIe-4143 module is an essential tool in modern electronic testing. Whether you’re working on semiconductors, battery devices, or IoT products, it offers a powerful and flexible solution. Being part of the larger PXI Modules family means it easily fits into modular test systems, helping you save space, improve performance, and simplify your testing setup.
If you are looking for a high-quality, reliable source measure unit, the PXIe-4143 is definitely worth considering.
