Description
The PCI-4474 is a high-performance, PC-based Sound and Vibration Device designed to cater to a wide range of sound and vibration analysis requirements. This device is identified by two part numbers, 778729-01 and 778778-01, ensuring flexibility and compatibility for various setups.
It features 4 Differential Channels for analog input, providing the capacity to handle multiple signals simultaneously. Each channel is equipped with 24-bit ADCs (Analog-to-Digital Converters), ensuring high-resolution data acquisition. The device boasts a maximum sampling rate of 102.4 kS/s (kilo-samples per second), allowing for the capture of fast-changing signals.
The dynamic range of the PCI-4474 is impressive, offering greater than 110 dB when using a 16k FFT at a 51.2 kS/s sampling rate. This wide dynamic range is essential for accurately capturing the nuances of both low-level and high-level signals. The ADC type utilized is Delta-Sigma, known for its high fidelity and precision.
Flexibility in signal acquisition is further enhanced by software-selectable AC/DC coupling and a high pass filter with a cutoff frequency of 3.4 Hz. This allows users to effectively filter out unwanted low-frequency noise and adapt the device for a variety of measurement scenarios.
Connection to the device is facilitated through SMB Front Connectors, which provide a secure and reliable physical interface. To achieve optimum performance, it is recommended that the PCI-4474 is allowed a warm-up time of 15 minutes.
Calibration is a critical aspect of ensuring accurate measurements. The PCI-4474 is self-calibrated on software command, with an external calibration recommended annually to maintain accuracy and reliability. Compatibility with various software platforms, including NI-DAQmx, LabVIEW, LabWindows/CVI, and Measurement Studio, ensures that the device can be easily integrated into a wide range of measurement and analysis systems.
