Description
The PXIe-4468 is a state-of-the-art PXI Dynamic Signal Acquisition (DSA) device designed for sophisticated sound and vibration analysis. This device comes with multiple part numbers, including 136687B-01L, 788512-01, and 788511-01, catering to different connector types and system requirements.
For connectivity, it offers two types of front connectors. The Mini-XLR Front Connector is associated with part number 788512-01, while the BNC Front Connector comes with part number 788511-01. This flexibility ensures compatibility with a wide range of sensor types and connection preferences.
At its core, the PXIe-4468 features Two-Channel Dynamic Signal Generation and Acquisition, supporting intricate multi-channel tests and analyses. Users can benefit from six gain settings, allowing for precise control over signal amplification to match the requirements of various test scenarios.
Moreover, the device supports both AC and DC coupling, offering versatility in signal acquisition methodologies. It also includes IEPE conditioning, enabling direct connection with sensors that require constant current excitation.
A built-in tone generator is available for system calibration and testing, enhancing the device’s utility in complex measurement setups. The PXIe-4468’s output stage can be configured in either differential or pseudodifferential mode, providing flexibility in addressing different signal integrity requirements.
In pseudodifferential mode, it features both manual and software gain correction, with a correction factor of -22.0 mdB. While software gain correction is automatically applied, manual gain correction requires user intervention, offering additional control over the measurement process.
Lastly, the device benefits from improved common-mode noise rejection when the chassis ground is connected to the input device ground, ensuring cleaner, more reliable data acquisition in electrically noisy environments.
