Description
The National Instruments PCI-4461 Sound and Vibration Device, with part number 779307-01, is a high-performance, two-channel dynamic signal generator and acquisition system. This device is designed specifically for applications such as sound tests, automotive tests, NVH (Noise, Vibration, and Harshness) analysis, and machine condition monitoring.
It features six pick-up input range settings, allowing for a wide variety of sensors to be used. The coupling is AC/DC and can be configured via software, providing flexibility for different test setups. The PCI-4461 is equipped with integrated IEPE (Integrated Electronics Piezo-Electric) conditioning, making it suitable for use with IEPE sensors without the need for external signal conditioning equipment.
The device boasts 24-bit Analog-to-Digital Converters (ADCs) for high-resolution data acquisition. It supports a variety of sampling rates including 44.1 kS/s, 48.0 kS/s, 96.0 kS/s, and up to 192 kS/s, offering versatility for different analysis needs. The delta–sigma ADC type ensures accurate data representation over a wide dynamic range.
Users can select gains from -20 to +30 dB in 10 dB steps, giving them control over signal amplification. The input connection can be either differential or single-ended, providing compatibility with a broad range of sensor types. With a dynamic range of 118 dB and a frequency range from DC to 92 kHz, the PCI-4461 is capable of capturing high-quality data across a wide spectrum of applications.
