The National Instruments PXI-449x / PXIe-449x Series Sound and Vibration Data Acquisition Modules are specifically designed for sound and vibration applications. With sixteen 24-bit analog inputs per module and IEPE constant current signal conditioning, National Instruments 449x modules are ideal for making precision measurements with microphones, accelerometers, and other transducers that have very large dynamic ranges. The modules deliver up to 114 dB of dynamic range and simultaneous sampling on all 16 channels at rates up to 204.8 kS/s. In addition, the modules include built-in antialiasing filters that automatically adjust to your sampling rate and software-selectable input gains up to 30 dB. Common applications for National Instruments 449x modules include in-vehicle acoustic test; noise, vibration, and harshness (NVH) analysis; large microphone arrays; and dynamic structural test. These modules are compatible with National Instruments Sound and Vibration Measurement Suite analysis software to complete your application with a variety of time and frequency measurements including octave and order analysis.
