The NI PXI-4461 is a 24-bit analog input/output data acquisition module for the PXI platform. It allows engineers to simultaneously generate and acquire high-accuracy dynamic signals for sound and vibration measurements. The PXI-4461 module features delta sigma converters that deliver nearly 120 dB dynamic range over an input bandwidth of 92 kHz at 204.8 kS/s. Its two differential output channels generate frequencies up to 92 kHz, making it suitable for shaker control and stimulus response tests such as swept-sine.
