Description
The PCI-4451 is a legacy Data Acquisition (DAQ) device that comes with a part number 18501.4 (777534-01). This device falls under the category of Legacy DAQ Devices, which signifies its importance in the history and development of data acquisition technology.
The PCI-4451 model is designed with 2 input channels and 2 output channels, making it versatile for a variety of applications. It boasts a remarkable dynamic range of 90 dB, ensuring high-quality signal acquisition and processing capabilities. The amplitude flatness is maintained at ±0.1 dB from DC to 95 kHz, which indicates a very consistent performance across a wide frequency range.
When it comes to Total Harmonic Distortion (THD), the PCI-4451 performs impressively with a THD of -90 dB at 1 kHz and -80 dB at higher frequencies. This level of performance highlights the device’s ability to produce clean and accurate signals.
The resolution of this device is 16-bit, which is sufficient for capturing detailed data. Furthermore, it supports sampling rates ranging from 5.0 to 204.8 kS/s, offering flexibility in data acquisition speed to suit different requirements.
Among its notable features are overload detection, AC/DC coupling, the ability for multiple-board synchronization, and 8 5V TTL/CMOS digital lines. These features enhance the device’s functionality and adaptability in complex DAQ systems.
Although it has been announced as obsolete by National Instruments, the PCI-4451 remains available for purchase and repairs through Apex Waves. This ensures that users can continue to benefit from its robust performance and features in their data acquisition tasks.
