Description
The Part Number 779748-01 refers to a high-quality PXI DSA device, specifically the model PXI-4496. This device is designed for precise data acquisition tasks, offering a 24-bit resolution and a sampling rate of 204.8 kS/s. It is equipped with 16 input channels and supports 2 gain settings, making it versatile for various measurement needs.
The PXI-4496 is tailored for high-fidelity measurements, featuring a dynamic range up to 114 dB and employs TEDS for intelligent sensor management. Its AC-Coupled inputs ensure that only the AC component of the signal is measured, filtering out any DC bias that might be present. This is especially useful in applications where the DC component is not of interest.
For signal conditioning, the device uses IEPE constant current sourcing, which is essential for powering piezoelectric sensors. The A/D conversion is achieved through Delta-sigma modulation, ensuring high accuracy and low noise in the digital representation of the analog signals. Furthermore, the device incorporates both analog and digital hardware filters for effective antialiasing, ensuring the integrity of the measured signal by removing frequencies higher than the Nyquist frequency.
