The PXI (PCI eXtensions for Instrumentation) is a high-performance modular platform aimed at test automation, data acquisition, and industrial instrumentation. Based on the PCI bus, PXI offers low latency, high precision, and deterministic synchronization — making it ideal for complex and multi-channel applications.
PXI is the gold standard for automated test applications in demanding and high-volume environments.
🧩 PXI System Features
- Modular architecture with chassis, controller, and I/O modules
- Support for hundreds of modules: DMMs, oscilloscopes, programmable power supplies, switches, signal generators, etc.
- High-speed communication via PCI/PXI Express bus
- Precise synchronization between channels and instruments with deterministic backplane
- Compatible with LabVIEW, TestStand, C#, Python, and other development environments
🛠️ Typical PXI Applications
| Sector | Common PXI Applications |

| Industrial Electronics | Functional tests (FT), voltage and current measurement, load simulation |
| Telecommunications | RF analysis, BER, modulation and protocol testing |
| Automotive | ECU testing, LIN, CAN, power control, and sensor simulation |
| Aerospace / Defense | Radar testing, RF, mission control, and complex system diagnostics |
| Laboratories and R&D | Multi-channel data acquisition with precise synchronization |
🔧 How AJOLLY Testing Uses PXI
At AJOLLY Testing, PXI is the main platform for high-complexity test benches, where the following are required:
- High sampling rate and precision
- Integration with multiple sensors and sources
- Synchronized control of various instruments
- Management of large volumes of data in real-time
Examples:
- Test benches with National Instruments PXI modules (e.g., NI PXIe-4080, 6363, 5412)
- Projects with programmable switching via PXI-switch
- Integration with TestStand + database + DUT traceability
✅ PXI Advantages
