National Instruments 780421-01 Sound and Vibration Device
National Instruments part number 780421-01 is an identifying part number for the USB-4432, a Sound and Vibration Device. The NI 780421-01 is a 0.8 Hz AC/DC Coupled, 5- Input device with a Sampling Range of 1 kS/s to 102.4 kS/s. This part is tailored for sound and vibration measurements.
Four of its input channels feature integrated electronic piezoelectric (IEPE) signal conditioning for accelerometers and microphones, along with built-in antialiasing filters that automatically adjust to the sampling rate. The fifth input channel lacks IEPE support. This device comes with an Analog Input (AI) Common-Mode Rejection Ratio (CMRR) of 45 dB for frequencies ranging from 20 Hz to 1 kHz.
The AI Distortion Plus Noise (THD+N) characteristics of the device vary with the input signal frequency (fin). For input signals between 20 Hz and 20 kHz, the typical Total Harmonic Distortion (THD) is -97 dB, with a maximum of -91 dB, while the THD+N is typically -92 dB and can reach up to -86 dB. For input signals between 20 Hz and 46.4 kHz, the typical THD is -95 dB, with a maximum of -89 dB, and the THD+N is typically -91 dB, with a maximum of -85 dB.
The AI spurious free dynamic range (SFDR) for a -1 dBFS, 1 kHz tone at the same sampling frequency is 104 dB. This device features four input channels: AI0, AI1, AI2, and AI3. Each channel can independently have a current setting of either 0 or 2.1 mA, selectable through software. The compliance voltage for the channels is a minimum of 20 V. The output impedance is 200 kΩ at 1 kHz. Additionally, this device offers an AI dynamic range of 101 dB typical and a minimum of 99 dB for a -60 dBFS, 1 kHz tone at a sampling frequency of 102.4 kS/s.
