{"product_id":"national-instruments-788511-01","title":"National Instruments 788511-01","description":"\u003cp\u003eThe National Instruments 788511-01 Sound and Vibration Module, also known as the PXIe-4468, is engineered for high-precision measurements in sound and vibration applications. This module features two simultaneously sampled input channels which support both differential and pseudodifferential configurations, complimented by software-selectable AC\/DC coupling. Utilizing a 24-bit delta-sigma analog-to-digital converter (ADC), it accommodates sampling rates from 100 S\/s to 250 kS\/s. The 788511-01 offers six gain settings for flexible input range configurations and provides maximum overvoltage protection of ±42.4 V peak.\u003c\/p\u003e\n\n\u003cp\u003eIn addition to input capabilities, the module includes two simultaneous analog output channels that can be configured in differential or pseudodifferential mode, supporting AC and DC coupling with 24-bit delta-sigma digital-to-analog converters (DACs). Output sample rates range from 100 S\/s to 200 kS\/s, and the channels also feature software-selectable attenuation. A FIFO buffer of 1,023 samples enhances data transfer efficiency via direct memory access (DMA) or programmed I\/O.\u003c\/p\u003e\n\n\u003cp\u003eThe input amplifier characteristics ensure reliable signal integrity, boasting high input impedance and a common-mode rejection ratio (CMRR). The module achieves an alias-free bandwidth of up to 101.536 kHz and an impressive alias rejection of 105 dBc. Compatibility with Transducer Electronic Data Sheet (TEDS) under the IEEE 1451 Standard and a maximum load capacitance of 10,000 pF further augment its capabilities. It also provides analog and digital triggering features for precise event detection and synchronization across multiple channels. \u003c\/p\u003e\n\n\u003cp\u003eDesigned to fit into various PXI Express and hybrid slots, the 788511-01 is housed in a compact 3U form factor with dimensions of 16 cm x 10 cm (6.3 in. x 3.9 in.) and a weight of 360 g (12.7 oz.). The unit operates effectively within a temperature range of 0 °C to 55 °C and has a maximum installation altitude of 2,000 meters above sea level. The 788511-01 is particularly suited for audio testing, automotive noise and vibration analysis, and machine condition monitoring applications.\u003c\/p\u003e","brand":"National Instruments","offers":[{"title":"Default Title","offer_id":46683838873836,"sku":"788511-01","price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0217\/1112\/6600\/files\/National_Instruments_Group_Photo_-_Final_Compressed_3e8ed6d4-6cf4-43ab-9860-bb929caa03e8.jpg?v=1753243091","url":"https:\/\/www.industrialautomationco.com\/products\/national-instruments-788511-01","provider":"Industrial Automation Co.","version":"1.0","type":"link"}
