Product Description
National Instruments PXIe-4468 PXI Sound and Vibration Module
The National Instruments PXIe-4468 (Part Numbers: 788512-01, 788511-01) is an advanced PXI sound and vibration module designed for high-precision measurements using microphones, accelerometers, and other sensors with large dynamic ranges. This versatile module meets the requirements of various sound and vibration applications including audio testing, automotive NVH, and machine condition monitoring.
Key Features
- Two channels of dynamic signal generation and two channels of acquisition
- Six configurable gain settings for input range adaptation
- AC/DC coupling and IEPE conditioning capabilities
- Built-in tone generator for comprehensive testing
- Differential amplifier output stage with software-configurable pseudodifferential mode
- Excellent common-mode noise rejection when properly grounded
Technical Specifications

Connector Options
The PXIe-4468 is available with two front connector options: Part number 788512-01 features Mini-XLR connectors, while part number 788511-01 uses BNC connectors.
Optimal Configuration
For best performance, configure the output stage in differential mode. When using pseudodifferential mode, note the -22.0 mdB gain difference that is automatically corrected by software. Proper grounding between the module chassis and input device is critical for optimal common-mode noise rejection, especially with isolated input devices.
This comprehensive solution combines multiple channels, configurable gain settings, and software-controlled features to deliver highly accurate and reliable results for demanding sound and vibration testing applications.
