24-Bit, 204.8 kS/s Dynamic Signal Acquisition and Generation.

Overview
The National Instruments 4461 is a high-accuracy data acquisition device specifically designed for sound and vibration applications. Common applications for the NI 4461 include audio test, automotive test, noise, vibration, and harshness (NVH) analysis, and machine condition monitoring (MCM). Ideal for applications where simultaneous generation and acquisition of noise, vibration, and acoustic signals are required. You can synchronize the acquisition clock of your NI 4461 with other instruments in your system for mixed-signal applications. Both analog and digital triggering are available on an NI 4461.
