Description
The Part Number for the device is 199108C-05L, which is also referred to as 781370-01 within the product description. This device falls under the Category of PXI DSA, specifically modeled as the PXIe-4499. It is designed as a PXI Sound and Vibration Module, which utilizes advanced technology for precise sound and vibration analysis.
The module incorporates Delta-sigma ADCs with oversampled engineering, which ensures high-fidelity data conversion from analog to digital format. To further refine the signal, the module employs both digital and analog lowpass filters. A unique feature of its digital filters is the ability to adjust cut-off frequencies in relation to the sampling rate, enhancing the module’s flexibility in handling various signal types.
An additional capability of the PXIe-4499 is its AI.RemoveFilterDelay property, which aligns the first acquired sample precisely with the digital trigger, ensuring accurate timing for analyses. The module’s trigger feature is robust, offering internal trigger generation that can be configured based on the crossing of input signal thresholds.
Furthermore, the module supports enhanced synchronization capabilities through its Trigger Bus Compatibility. It can route its internal trigger to the PXIe-4499 trigger bus, allowing seamless synchronization with other devices within the PXI system. This feature is essential for complex measurement tasks requiring coordinated data acquisition from multiple sources.
