Key Advantages & Features

• Ultra-High Precision: 22-bit resolution and industry-leading accuracy ensure reliable measurements for critical test applications.
• Fast Sampling & Scanning: 1 MS/s single-point sampling and continuous data acquisition support high-throughput testing.
• Seamless PXIe Integration: Synchronizes with other PXIe modules (e.g., signal generators, oscilloscopes) via the PXIe trigger bus for synchronized test workflows.
• Software Compatibility: Works with NI’s software ecosystem and third-party tools via IVI drivers, reducing test program development time.
• Built-in Self-Calibration: Automatically corrects for drift over time and temperature, eliminating the need for frequent manual calibration.
• Rugged & Compact Design: 3U PXIe form factor saves chassis space, while CAT III input protection ensures safety in industrial environments.
• Multi-Function Versatility: Combines voltage, current, resistance, and frequency measurements in one module, reducing the need for multiple test instruments.

Application Examples

• Aerospace & Defense: Testing avionics components (e.g., power supplies, sensors) for voltage/current stability and signal integrity.
• Automotive Electronics: Validating ECU (Electronic Control Unit) performance, battery management systems, and infotainment module power consumption.
• Electronics Manufacturing: In-line testing of PCBs, semiconductors, and consumer electronics for component functionality and parametric compliance.
• Research & Development: Precision measurements for academic research, material science, and prototype validation (e.g., sensor characterization).
• Industrial Automation: Calibrating PLCs, industrial sensors, and process control devices to ensure operational accuracy.

Comparison with Competitors

• Keysight 34972A (Data Acquisition/Switch Unit): NI PXIE-4080 offers faster sampling rates (1 MS/s vs. 100 kS/s) and deeper PXIe integration, while the 34972A is a standalone benchtop/rack-mount unit with switch capabilities.
• Tektronix DMM4040 (Benchtop DMM): The PXIE-4080 provides better integration with automated test systems, whereas the DMM4040 is optimized for manual benchtop use.
• Keithley 2450 (Source Measure Unit): While Keithley 2450 adds source capabilities, NI PXIE-4080 excels in high-speed sampling and PXIe ecosystem compatibility for multi-instrument test setups.
• Value Proposition: NI’s software-hardware synergy (e.g., LabVIEW integration) and modular design make NI PXIE-4080 more scalable for complex, evolving test requirements compared to standalone DMMs.

Selection & Usage Recommendations

• Ensure compatibility with your PXIe chassis (check NI’s chassis compatibility list for NI PXIE-4080).
• Choose the appropriate input protection (CAT II/CAT III) based on your application’s voltage environment.
• Use NI LabVIEW or TestStand for seamless integration and to leverage built-in measurement libraries.
• Schedule regular self-calibration (e.g., monthly) to maintain measurement accuracy, especially in temperature-variable environments.
• Avoid exceeding input voltage/current limits to prevent damage—utilize the module’s built-in overrange protection alerts.
• Pair with NI PXIe trigger modules for synchronized multi-instrument testing (e.g., with signal generators or oscilloscopes).
• Update firmware and drivers regularly via NI Package Manager to access new features and performance improvements.
