Description
The National Instruments PXIe-4499 is a highly capable PXI Sound and Vibration Module, designed to meet a wide range of testing requirements. With part numbers 199108D-05L, 781370-01, this module falls under the category of PXI DSA, highlighting its specialized design for dynamic signal analysis.
At the core of the PXIe-4499’s functionality is its ability to handle sound and vibration signals with precision. This is largely due to its advanced ADC (Analog-to-Digital Converter) technology. The module uses Delta-sigma ADCs equipped with oversampled engineering, which is pivotal for testing signals that exceed the Nyquist Limit. This technical choice ensures that the data captured is both accurate and reliable, making the module an excellent choice for demanding testing environments.
To further enhance its performance, the PXiE-4499 incorporates both digital and analog lowpass filters. These filters are crucial for eliminating aliasing, a common issue in signal processing that can significantly distort the results. Moreover, the module’s filter adaptation capabilities automatically adjust the digital filter to follow the Nyquist frequency, thereby optimizing performance without manual intervention.
An interesting feature of the PXIe-4499 is its support for the AI.RemoveFilterDelay property. This allows for precise data alignment with the digital trigger, ensuring that the timing of data collection is both accurate and consistent. Furthermore, the module’s triggering capabilities allow for the creation of internal digital triggers, independent of the input signal level. This feature is particularly useful in scenarios where signal levels can be unpredictable or varied.
Last but not least, the synchronization feature of the PXIe-4499 cannot be overlooked. It provides the capability to synchronize acquisition tasks across multiple devices via an internal trigger. This is especially beneficial in complex testing setups where coordination between different instruments is necessary.
In conclusion, the National Instruments PXIe-4499 PXI Sound and Vibration Module is a sophisticated tool designed for high-precision testing. Its advanced ADC technology, combined with effective filtering, adaptable trigger systems, and synchronization capabilities, make it
