The National Instruments PCI-4472 is an advanced 8-channel sound and vibration device designed for precision signal acquisition in various applications such as pass-by noise testing, vibration diagnostics, structural analysis, audio measurement, telecommunications, sound power assessment, and machine condition monitoring. Featuring both pretrigger and posttrigger modes, this device enables effective acquisition of transient signals by digitizing data either before or after a specified trigger condition. With a sampling rate of 102.4 kS/s, the PCI-4472 ensures high-fidelity data collection, supported by a robust 5 V TTL/CMOS-compatible external trigger interface, adjustable for incrementing or decrementing edge conditions. The unit can be synchronized with multiple NI-447x devices to facilitate high-channel-count applications.

Additionally, the PCI-4472 employs a precision voltage reference to maintain stability in gain and balance, optimizing measurement accuracy. It seamlessly integrates with NI's measurement services software based on the NI-DAQmx driver, allowing users to develop automated test systems or interface with other hardware. The DAQ Assistant tool provides an intuitive guide through tasks related to configuration, analysis, and programming, generating necessary code for National Instruments applications. The PCI-4472 is in a mature status, which means it remains available for purchase and repairs through Apex Waves. Each device is backed by a three-year warranty, and user and maintenance manuals are available for download, ensuring comprehensive support for implementation and operation. The dimensions of the PCI-4472 are 6.9 x 4.2 inches and it weighs 7 ounces. For pricing information, please contact a sales representative.
