Analog Inputs

The analog input channels of NI 446x devices have 24-bit resolution ADCs that are simultaneously sampled at software-programmable rates for standard audio applications, such as 44.1 kS/s (the standard rate used in CD players), 48.0 kS/s (the rate used in digital audio tape (DAT) recorders and other digital audio equipment), 96.0 kS/s, and 192 kS/s. An NI 446x is well-suited for audio, sound, and vibration analysis applications. The analog inputs offer programmable AC/DC coupling. A programmable gain amplifier stage on the inputs gives gain selection from -20 to +30 dB in 10 dB steps. Furthermore, to provide you with the quietest and highest-quality analog measurements, the input stage accepts differential or single-ended signal connections. With 118 dB dynamic range and low noise and distortion, NI 446x devices can make very accurate frequency-domain measurements. They have excellent amplitude flatness of ±0.1 dB within the frequency range of DC to 92 kHz, and have a typical THD of -107 dB.
