Part Number: 778442-01
The National Instruments 778442-01 PXI-4461 Sound and Vibration Module is a high-performance device specifically designed for sound and vibration analysis in various industrial applications. It features two independently selectable input channels, allowing for AC or DC coupling, making it highly versatile for applications ranging from machine status monitoring to audio testing. The module is equipped with accelerometers and microphones, along with the necessary hardware to ensure precise measurements. Connectivity options include female BNC connectors for analog input/output and a male SMB connector for digital trigger inputs.

Each channel of the PXI-4461 can be configured by the user with adjustable input ranges across six gain levels. The module supports two analog output and two analog input channels, capable of both differential and pseudodifferential configurations with a 50 Ω impedance to chassis ground. Featuring a 24-bit resolution delta-sigma analog-to-digital converter, the module provides high fidelity in data acquisition. Its FIFO buffer accommodates up to 2,047 samples, with data transfer managed via direct memory access (DMA) for optimal performance.

Compactly designed to fit within a 3U CompactPCI slot, the dimensions of the PXI-4461 measure 16 cm × 10 cm (6.3 in. × 3.9 in.), and it weighs only 241 g (8.5 oz). The device operates effectively in environments with temperatures ranging from 0 to 55 °C (32 °F to 131 °F). The National Instruments 778442-01 is backed by a three-year warranty, ensuring reliability in demanding measurement applications.
