Description
The National Instruments PXI-4461 is a PXI Sound and Vibration Module designed for high-precision applications. This module, identified by the part number 779687-01, falls under the category of PXI DSA, which stands for Dynamic Signal Acquisition. The PXI-4461 is specifically engineered to handle two-channel dynamic signal generation and acquisition, making it a versatile choice for a wide range of sound and vibration analysis tasks.
One of the key features of this module is its input range design, which allows users to select from one of six gain settings. This flexibility ensures that the module can be adapted to various signal strengths with ease. Additionally, the coupling is programmable for either AC or DC, providing further adaptability depending on the nature of the signal being measured. For applications requiring IEPE (Integrated Electronics Piezo-Electric) sensors, the PXI-4461 incorporates IEPE conditioning, streamlining the setup and ensuring accurate measurements.
The terminal configurations for AI (Analog Input) include both differential and pseudo-differential options, catering to diverse wiring requirements. Moreover, this module maintains a resistance of 50 Ω between the outer BNC shell and the chassis frame, which is crucial for minimizing noise and ensuring signal integrity. To protect against aliasing, digital filters are available, enhancing the quality of the acquired data.
Another significant feature of the PXI-4461 is its support for acquisition clock synchronization, which is essential for synchronized data collection across multiple channels or devices. The module also offers versatile triggering options, including both digital and analog triggers, to accommodate various start and stop conditions for data acquisition. With a 24-bit ADC (Analog-to-Digital Converter), the PXI-4461 ensures high-resolution data capture, preserving the details of the signal.
The module’s sampling rates are software-programmable, including common rates such as 44.1 kS/s and 48.0 kS/s, which are frequently used in audio applications. This programmability allows users to finely tune the data acquisition process to match specific
