The National Instruments PCI-4454 Dynamic Signal Acquisition Device is engineered for high-accuracy measurements in varied dynamic data acquisition applications. Designed to operate with the PCI bus, the PCI-4454 features four analog single-ended input channels that can be software-configured for enhanced versatility. Each input channel supports both AC and DC coupling modes via a programmable switch, accommodating a voltage range of -10 V to +10 V with a maximum input range of 20 V. The device excels in sampling speed, offering simultaneous data acquisition at rates up to 51.2 kS/s and maintaining a bandwidth of DC to 23 kHz. With a resolution of 16 bits, the PCI-4454 is ideal for high-fidelity signal processing, making it suitable for applications in audio signal analysis, acoustics research, speech processing, sonar applications, and vibration analysis. The device is equipped with precision delta-sigma converters operated at optimal clock rates, along with an integrated self-calibration feature that mitigates offset and gain errors. Although the PCI-4454 has been declared obsolete by National Instruments, it remains available for purchase and repair through Apex Waves, along with user manuals available for download.
