Part Number: 779747-01

The National Instruments 779747-01 PXI Sound and Vibration Module, also known as the NI 4498, is a high-performance device designed for analog input in data acquisition systems. This module boasts 16 simultaneously sampled input channels, facilitating efficient data acquisition and analysis across multiple channels. With AC-only input coupling, the 779747-01 is compatible with a wide array of signal sources, making it suitable for various modern test and measurement applications. It features a 24-bit resolution Delta-sigma ADC and employs a pseudodifferential input configuration, with a 50 Ω impedance between the chassis ground and the negative input. The FIFO buffer supports a size of 4,095 samples, enabling streamlined data transfer and processing.

Flexibility is a hallmark of the 779747-01, as it offers sample rates ranging from 100 S/s to 204.8 kS/s to accommodate specific measurement requirements. The module is compact, measuring 16 cm × 10 cm (6.3 in. × 3.9 in.) and weighing only 326 g (11.5 oz). Optimal operating conditions are maintained within a temperature range of 0 °C to 55 °C and a relative humidity of 10% to 90% (non-condensing), while safe storage can occur at temperatures between –20 °C and 70 °C with a relative humidity from 5% to 95% (non-condensing). The 779747-01 is backed by a three-year warranty, reflecting National Instruments' commitment to quality and reliability in industrial automation and control systems.
