Description
The PXI-4461 is a dynamic signal analyzer designed for sound and vibration applications, featuring a part number of 186900M-01L, 779687-01. This device falls under the category of PXI DSA and is equipped with 2-channel dynamic signal generation and 2-channel acquisition, making it highly versatile for various testing scenarios.
One of the key specifications of the PXI-4461 is its input range design, which allows for one of six gain settings, providing flexibility in accommodating signals of different amplitudes. Additionally, it offers programmable configurable AC/DC coupling and IEPE conditioning, catering to a wide range of sensor types and signal conditioning requirements.
The device supports both differential and pseudo-differential terminal arrangements for analog inputs (AI), ensuring compatibility with different sensor and wiring configurations. Moreover, it maintains a 50 Ω resistance between the outer BNC shell and the chassis frame, which is crucial for maintaining signal integrity and minimizing noise.
To protect against aliasing, the PXI-4461 incorporates digital filters, ensuring that only the desired signal frequencies are sampled and analyzed. Users can configure channels on a per-channel basis, choosing between differential or pseudo-differential modes according to the application’s requirements.
A significant feature of the PXI-4461 is its capability for synchronization, allowing the acquisition clock to be synchronized with other devices, which is essential for multi-channel and phased-array measurements. The device also supports both digital and analog triggering, providing flexibility in starting acquisitions based on complex signal conditions.
The high 24-bit resolution of its analog-to-digital converters ensures precise data capture, enabling detailed analysis of signal nuances. Furthermore, it offers software-programmable sampling rates, such as 44.1 kS/s and 48.0 kS/s, allowing users to optimize the balance between resolution and data throughput according to the application’s demands.
