The National Instruments PXI-4461 is a high-accuracy data acquisition module specifically designed for sound and vibration applications. This module includes the hardware and software needed to make precision measurements with microphones, accelerometers, and other transducers that have very large dynamic ranges. Common applications include audio test, automotive NVH, and machine condition monitoring.

Best Value: Buy both and save.
The NI PXI-4461 is also available as a bundle with the NI Sound and Vibration Measurement Suite, which includes NI Sound and Vibration Assistant, at a discount from the list price. See the Resources tab for more information on the list of analysis capabilities of the Sound and Vibration Measurement Suite.

Multidevice Synchronization
For applications requiring up to thousands of channels, you can synchronize the operation of two or more NI 446x devices with less than 0.1 deg of phase mismatch between channels.

Hybrid Slot-Compatible PXI Modules
The NI PXI-4461 is available in both PXI and PXI Express hybrid slot-compatible form factors. You can use the hybrid slot-compatible PXI-446x modules in PXI slots, CompactPCI slots, and hybrid slots, found in new PXI Express chassis.
