Description
The Part Number 779687-01 identifies a specific PXI Dynamic Signal Analyzer (DSA), known as the PXI-4461. This device is categorized under PXI DSA and is designed to fit into a Base Board (Hybrid Slot) within the PXI system chassis.
This model features two-channel dynamic signal generation and acquisition, providing flexibility for a wide range of applications. Users can select from one of six gain settings in the input range design, allowing for optimization based on the signal levels being measured or generated.
For signal conditioning, the PXI-4461 offers programmable AC/DC coupling and IEPE conditioning, making it suitable for complex signal analysis tasks. It is particularly well-suited for applications such as audio test, automotive NVH (Noise, Vibration, and Harshness), and machine condition monitoring.
The device supports both differential and pseudo-differential terminal arrangements for analog inputs (AI), ensuring compatibility with a wide range of sensor types. Moreover, it maintains a 50 Ω resistance between the BNC shell and the chassis frame, which helps in minimizing noise and ensuring signal integrity.
To prevent aliasing, the PXI-4461 is equipped with digital filters, enhancing the quality of the signal captured or generated. It boasts 24-bit resolution ADCs (Analog-to-Digital Converters), providing high-precision measurements.
The device allows for software-programmable sampling rates, such as 44.1 kS/s and 48.0 kS/s, offering flexibility for various data acquisition tasks. Lastly, to ensure continued accuracy and performance, calibration of the PXI-4461 is available and is recommended to be performed annually or every two years.
