Description
The National Instruments PXIe-4498 PXI Sound and Vibration Module is a specialized device designed for high-channel count sound and vibration applications, including noise, vibration, and harshness analysis, dynamic structural testing, and the use of large microphone arrays. With part numbers 780218-01 and 780218-02, this module boasts 16 simultaneously sampled analog inputs that ensure high-fidelity data acquisition.
The module’s analog-to-digital conversion is handled by a high-precision 24-bit delta-sigma ADC, which delivers the accuracy required for the most demanding audio and vibration analysis tasks. The sampling rate is software-programmable, and features an automatic cutoff frequency adjustment to match the needs of various applications.
To protect against aliasing, fixed analog filters are utilized, negating the need for additional external filtering. The PXIe-4498 is also equipped with versatile triggering modes, including both analog and digital signal triggering as well as a start trigger mode for capturing transient signals. The external digital trigger is 5 V TTL/CMOS-compatible and can be set to respond to either a rising or falling edge, providing flexibility in system integration and synchronization.
