Description
The Part Number 189545C-01 refers to a high-performance PC-based Dynamic Signal Analyzer (DSA), specifically the model PCI-4474. This device is tailored for precise and dynamic data acquisition tasks, showcasing its capabilities through a 24-bit Analog-to-Digital Converter (ADC) that achieves a maximum sampling rate of 102.4 kS/s.
The PCI-4474 model is distinguished by its four simultaneously sampled differential analog inputs, designed to facilitate accurate and synchronized data collection. The dynamic range of this DSA exceeds 110 dB, highlighting its ability to discern fine details within a wide range of signal amplitudes. This remarkable sensitivity is partially attributed to its Delta-Sigma ADC type, known for high fidelity signal processing.
Flexibility in signal analysis is further enhanced by the software-selectable AC/DC coupling, allowing users to tailor the device to a variety of measurement scenarios. The inclusion of a high pass filter with a cutoff frequency of 3.4 Hz aids in the reduction of low-frequency noise and drift, ensuring cleaner data capture. Connectivity is streamlined through SMB front connectors, facilitating easy and secure attachment to other devices and sensors.
For optimal performance, the PCI-4474 requires a warm-up time of 15 minutes, ensuring stability and accuracy in measurements. The device supports self-calibration via software commands, with an external calibration recommended annually to maintain its precision. Compatibility with NI-DAQmx, LabVIEW, LabWindows/CVI, and Measurement Studio software packages allows for seamless integration into existing data acquisition and analysis workflows, making the PCI-4474 an indispensable tool for engineers and researchers requiring high-precision signal analysis.
