National Instruments 781490-01 Sound and Vibration Module

The National Instruments 781490-01 is an 8-input sound and vibration module. It is designed for precision measurement tasks and is also known as the PXIe-4492 unit. It features 24-bit delta-sigma analog-to-digital converters (ADCs) with a high dynamic range that makes it ideal for capturing detailed sound and vibration data. The module supports a sampling rate range from 100 S/s to 204.8 kS/s along with a resolution of less than 181.9 μS/s that ensure accurate data acquisition across all channels simultaneously. Each of the eight input channels of this 781490-01 unit can be configured independently for AC or DC coupling. The input configuration is pseudodifferential that offers 50 Ω resistance between the negative input and chassis ground.

The NI 781490-01 includes integrated IEPE (Integrated Electronics Piezo-Electric) signal conditioning that provides 4 mA of constant current to power transducers such as accelerometers and microphones. This feature supports TEDS (Transducer Electronic Data Sheet) according to the IEEE 1451 standard that facilitates automated sensor setup and reducing the potential for configuration errors. The module's antialiasing filters are automatically adjusted to match the sample rate that ensure the integrity of the acquired data by preventing frequency distortion. The 781490-01 module offers exceptional performance in both AC and DC coupled measurements. The gain amplitude accuracy for AC coupled measurements at 1 kHz is maintained within 0.05 dB, while DC coupled measurements have a gain amplitudee accuracy of 0.5% within 5 °C of the last self-calibration temperature. The module also offers overvoltage protection along with the positive terminal tolerating up to ±30 V and the negative terminal up to ±5 V.

This sound and vibration unit comes in a compact design (16 cm × 10 cm) that allows it to fit within a 3U CompactPCI slot. It makes this 781490-01 unit suitable for integration into various PXI or PXI Express systems. It supports both analog and digital triggers that offers flexibility in synchronization and data capture across complex testing setups. The 781490-01 module is built for use in a wide range of environmental conditions. It’s operating temperature ranges from 0 °C to 55 °C along with relative humidity up to 90%. It is also compliant with several international safety and electromagnetic compatibility standards. This 781490-01 unit is particularly suited for applications like noise, vibration, and harshness (NVH) analysis, large-scale microphone arrays, and dynamic structural testing.
