Description
The part number 779307-01 refers to a PC-based Dynamic Signal Acquisition (DSA) device, specifically the PCI-4461 model. This product is a National Instruments PCI-4461 Sound and Vibration Device, designed to measure and analyze audio, acoustic, and vibrational signals.
The PCI-4461 features 2 AI (Analog Input) and 2 AO (Analog Output) channels. It supports both AC/DC Coupling and IEPE Conditioning, making it versatile for various types of signal inputs. The device boasts a high-resolution 24-bit ADC (Analog-to-Digital Converter), ensuring accurate data conversion for precise measurements.
Regarding sampling rates, the PCI-4461 can operate at 44.1 kS/s, 48.0 kS/s, 96.0 kS/s, and up to 192 kS/s, providing flexibility for different applications. It utilizes a Delta-Sigma ADC type, known for its high fidelity and low noise performance. Users can adjust the gain from -20 to +30 dB in 10 dB steps, allowing for optimal signal input levels.
The dynamic range of the PCI-4461 is an impressive 118 dB, and it can handle frequencies from DC to 92 kHz. This wide frequency range makes it suitable for a variety of sound and vibration analysis tasks. The device also exhibits a very low Total Harmonic Distortion (THD) of -107 dB, indicating its ability to accurately reproduce audio signals without distortion.
For triggering, the PCI-4461 supports both Analog and Digital triggering methods, providing versatility in capturing specific events or conditions during measurement. Lastly, the device weighs 8.5 oz, making it relatively lightweight and easy to install in various setups.
