NI PXIe-4492 PXI sound and vibration module Guaranteed Quality

The National Instruments PXIe-4492 is an 8-channel, 24-bit, 204.8 kS/s PXI sound and vibration module designed for making precision measurements with microphones, accelerometers, and other transducers that have very large dynamic ranges.

It features:

• High-resolution, 24-bit analog-to-digital converters (ADCs) for accurate signal capture
• Wide dynamic range of 113 dB for measuring a wide range of signal levels
• Two selectable input gains for optimizing signal levels for different transducers
• 0.5 Hz AC/DC coupling for measuring both AC and DC signals
• Built-in anti-aliasing filters to prevent signal distortion at high sampling rates
• Software-selectable input filters for further signal conditioning
• TEDS (Transducer Electronic Data Sheet) support for automatic sensor configuration
• Synchronous sampling on all channels for accurate phase measurements

The PXIe-4492 is ideal for a variety of sound and vibration applications, including:

• Noise, vibration, and harshness (NVH) analysis
• Large microphone array measurements
• Dynamic structural testing
• Machine condition monitoring
• Acoustic emission testing

It is also compatible with a wide range of National Instruments data acquisition software, including LabVIEW, DIAdem, and NI SignalExpress.
