The National Instruments PCI-4474 is a sound and vibration device featuring 4 differential analog input channels, 24-bit ADCs, a maximum sampling rate of 102.4 kS/s, dynamic range greater than 110 dB, delta-s
The National Instruments PCI-4474 Sound and Vibration Device is a specialized hardware tailored for precise sound and vibration analysis, featuring part numbers 778729-01 and 778778-01. This device is equipped with four differential analog input channels and utilizes high-resolution 24-bit Analog-to-Digital Converters (ADCs) to ensure accurate data acquisition, with a maximum sampling rate of 102.4 kS/s. Users can achieve a dynamic range of over 110 dB when utilizing a 16 k FFT at a sampling rate of 51.2 kS/s.
The advanced delta-sigma adjusting ADCs employed in this device are known for their low noise and low distortion characteristics, which are essential for high-fidelity measurements. With software-selectable AC/DC coupling and a 3.4 Hz high pass filter cutoff frequency, the PCI-4474 offers flexibility in signal processing. Connection to the device is made simple with SMB front connectors.
To ensure optimal performance, a warm-up time of 15 minutes is recommended before use, and the device supports self-calibration via software command. However, it is advised to perform external calibration at least once a year to maintain accuracy. The device is managed through the NI-DAQmx driver software, which is compatible with a variety of programming environments.
The PCI-4474 is lightweight at only 6.5 oz. and has compact physical dimensions of 6.9 x 4.2 inches, making it suitable for integration in a range of testing and measurement setups.
