The National Instruments 446x 24-bit dynamic signal acquisition (DSA) devices for sound and vibration measurements are designed for high-accuracy time- and frequency-domain measurements. With 118 dB dynamic range and six gain settings from ±316 mV to ±42 V, NI 446x devices are ideal for audio test applications including amplifier and ADC/DAC test. When combined with the NI Sound and Vibration Measurement Suite, NI 446x devices can perform noise emissions test, acoustic holography, frequency response, swept sine, and other analyses.
Recommended Software
NI sound and vibration analysis software, including the NI Sound and Vibration Measurement Suite and the NI Sound and Vibration Toolkit, provides signal processing functionality for performing audio measurements, fractional-octave analysis, frequency analysis, transient analysis, and order tracking.
