Description
The product with the part number 185014D-01, also known as the alternative part number 777534-01, falls under the category of Legacy DAQ Devices. It is identified by the model PCI-4451. This device boasts 2 input channels and 2 output channels, providing flexibility in data acquisition tasks.
It features a 16-bit resolution, ensuring precise data measurement and analysis. The sampling rates range from 5.0 to 204.8 kS/s, accommodating a variety of data speeds. With a dynamic range of 90 dB and a frequency range that extends from DC to 95 kHz, it is capable of capturing a wide spectrum of signals.
The Total Harmonic Distortion (THD) at 1 kHz stands at -90 dB, while at higher frequencies, it slightly decreases to -80 dB. The amplitude flatness is maintained at ±0.1 dB, ensuring consistency across the board. The device supports both AC and DC coupling, offering versatility in signal connection.
Notably, it features multiple-board synchronization, allowing for coordinated data acquisition across several devices. It also includes 8 5V TTL/CMOS lines for digital I/O, enhancing its integration capabilities. Although its production has been announced obsolete by National Instruments, it remains available for purchase and repairs via Apex Waves.
