Description
The PCI-4451 is a legacy DAQ device characterized by its unique part number 185014F-01, with an alternative part number 777534-01. This device falls under the category of Legacy DAQ Devices, showcasing its importance in historical data acquisition development and application.
It features 2 inputs and 2 outputs, providing a balanced approach for both data acquisition and signal output. The 16-bit resolution ensures that data is captured with high fidelity, translating to more precise and accurate measurements.
One of the key specifications of the PCI-4451 is its sampling rates, which range from 5.0 to 204.8 kS/s. This flexibility in sampling rates allows users to adjust the device according to the needs of their specific applications, from low-speed monitoring to high-speed data logging.
The device boasts a significant dynamic range of 90 dB and operates across a frequency range from DC to 95 kHz. These features ensure that it can handle a wide range of signals, from very low frequencies up to those approaching RF levels.
Regarding signal quality, the PCI-4451 maintains a Total Harmonic Distortion (THD) at -90 dB for 1 kHz signals and -80 dB for higher frequencies. Additionally, its amplitude flatness is rated at ±0.1 dB, indicating minimal deviation in amplification across its operating frequency range. These specifications underline the device’s ability to deliver high-quality, distortion-free signals.
The input and output channels can be AC/DC coupled, offering flexibility for various signal types. Furthermore, it includes 8 digital lines of 5V TTL/CMOS, expanding its utility for digital interfacing alongside analog signal processing.
Although its obsolete status has been announced by National Instruments, the PCI-4451 remains available from Apex Waves. This availability ensures that users can still access this powerful device for their legacy system needs, underscoring its enduring value in the field of data acquisition and signal processing.
