Description
The Part Number for this device is 199108C-01L, with alternative part numbers being 780218-01 and 780218-02. This device falls under the category of PXI DSA and is designated as the model PXIe-4498. Manufactured by National Instruments, the device is described as a PXI Sound and Vibration Module.
It is primarily used for applications such as noise, vibration, and harshness analysis, dynamic structural test, and managing large microphone arrays. One of the key features of this module is its Analog Inputs, which total 16. The module utilizes a 24-bit delta-sigma ADC Type for analog-to-digital conversion.
To ensure the integrity of the signal processing, the device offers digital filtering with a variable cutoff frequency and a software-programmable sampling rate. Moreover, both analog and digital filters are applied in hardware to prevent aliasing, ensuring high-quality data acquisition.
Another critical feature is the module’s Triggering capabilities, which include both analog and digital signal triggering. The trigger sources are versatile, encompassing analog input channels, an external digital trigger input, and the PXI trigger bus, with compatibility for 5 V TTL/CMOS. Users can select between rising or falling edge selection, providing flexibility in various testing and measurement scenarios.
