National Instruments NI PXI-4462 Dynamic signal analyzers: 4 Inputs

Overview 

The National Instruments 4461 and 4462 are high-accuracy data acquisition devices specifically designed for sound and vibration applications. The devices include the hardware and software needed to make precision measurements with microphones, accelerometers, and other transducers that have very large dynamic ranges. Common applications for the NI 446x include audio test, automotive test, noise, vibration, and harshness (NVH) analysis, and machine condition monitoring (MCM). The NI 446x devices offer a complete range of functionality for sound and vibration monitoring and analysis applications. With either two inputs and two outputs, or four inputs, they are 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 446x with other instruments in your system for mixed-signal applications. Both analog and digital triggering are available on an NI 446x.
