Description
The PXI-4461 is a high-performance, PXI Dynamic Signal Analyzer (DSA) designed for precision measurements and analysis. This device is specified with a part number 186900B-01, which was corrected from the initial part number 779687-01. It falls under the category of PXI DSA, offering a blend of flexibility and powerful signal processing capabilities.
With a 24 Bit resolution, the PXI-4461 provides highly accurate data conversion. This is complemented by a sampling rate of 204.8 kS/s, enabling the capture of high-frequency signals without the loss of information. The device is equipped with 2 input and 2 output channels, allowing for simultaneous signal generation and acquisition.
The dynamic range of the PXI-4461 is an impressive 118 dB, ensuring excellent signal fidelity and noise performance across a wide range of signal amplitudes. The input range design offers one of six gain settings, providing flexibility in handling various signal levels. Additionally, the input coupling can be set to either AC or DC programmable, enhancing the device’s versatility for different testing scenarios.
IEPE (Integrated Electronics Piezo-Electric) conditioning is included with the device, facilitating direct connection to IEPE sensors for vibration and acoustic measurements. The terminal arrangements for analog inputs support both differential and pseudo-differential configurations, allowing for improved signal integrity and reduced noise. Furthermore, the device ensures a resistance of 50 Ω between the BNC shell and the chassis frame, safeguarding against ground loops.
To enhance signal quality and prevent aliasing, digital filters are integrated into the PXI-4461. The analog-to-digital converters within the device boast 24-bit resolution and are simultaneously sampled, ensuring precise and synchronized data acquisition across all channels.
The PXI-4461 is ideally suited for various applications, including audio testing, automotive NVH (Noise, Vibration, and Harshness), and machine condition monitoring.
