Description
The National Instruments PCI-4451 Dynamic Signal Acquisition Device, part number 777534-01, is designed with two input and two output channels, providing a robust solution for a wide range of signal processing tasks. This device boasts an impressive dynamic range of 90 dB and maintains an amplitude flatness of ±0.1 dB across a frequency range from DC to 95 kHz, ensuring high-fidelity measurements.
With a 16-bit resolution and flexible sampling rates ranging from 5.0 to 204.8 kS/s, the PCI-4451 is capable of capturing and reproducing signals with high accuracy. The device’s total harmonic distortion (THD) is rated at -90 dB at 1 kHz and -80 dB at higher frequencies, highlighting its precision in signal analysis.
Additional features include overload detection, AC/DC signal coupling, and the capability for multi-board synchronization, which are essential for complex setups requiring precise timing and coordination between multiple devices. The inclusion of eight 5V TTL/CMOS digital I/O lines further extends its versatility in interfacing with other equipment.
Despite its obsolete status announced by National Instruments, the PCI-4451 remains available for purchase and support through Apex Waves, providing continued access to this high-quality signal acquisition device for existing and new applications.
