The National Instruments PXIe-4463 Sound and Vibration Module, identified by part number 783086-01, is a high-performance device designed for advanced sound and vibration measurement applications. This module features two output channels that can be configured as either differential or pseudodifferential through software control, allowing for versatile signal processing options. Each channel offers DC coupling and simultaneous sampling capabilities, which enhances its utility in dynamic testing environments. The integrated Delta-sigma digital-to-analog converter (DAC) boasts a resolution of 24 bits, supporting sample rates ranging from 100 samples per second (S/s) to 51.2 kS/s, with an oversampling rate of up to 520.833 kS/s.

Equipped with a 1023-sample FIFO buffer, the PXIe-4463 facilitates efficient data transfer via Direct Memory Access (DMA) or programmed I/O, ensuring seamless communication with other system components. The module is compatible with PXI Express chassis and hybrid slots, accommodating both PXI and PXI Express modules. It incorporates two timing engines and utilizes the onboard clock as its reference source. The power module operates at a maximum of 3A when powered by 3.3V and 2A at 12V.

Constructed with dimensions of 6.3 inches by 3.9 inches and weighing 18.5 ounces, the PXIe-4463 is suitable for indoor applications, operating optimally within an ambient temperature range of 0 °C to 55 °C and a relative humidity of 10% to 90% (noncondensing). Proper maintenance is essential; therefore, cleaning with a soft, nonmetallic brush is recommended prior to operation. For storage, the module can be safely housed at temperatures between -20 °C and 70 °C with a relative humidity range of 5% to 95% (noncondensing). The device features a self-calibration capability, which is advised whenever the ambient temperature deviates by more than ±5 °C from the last calibration point. The recommended external calibration interval is two years, and a warm-up time of 15 minutes is suggested before use.
