What are the design considerations for high-speed data acquisition systems?

High-speed DAQ considerations: sampling rate (Nyquist plus margin, anti-aliasing filters), ADC selection (flash or SAR for speed, sufficient resolution), aperture jitter (timing uncertainty degrades SNR at high frequencies), memory/throughput (buffer size, data transfer rate), triggering (precise timing for multi-channel synchronization), and analog front-end bandwidth. PCB design: controlled impedance traces, proper decoupling, separate analog and digital grounds. Data handling: DMA for continuous acquisition, hardware triggering for synchronization. Applications: vibration analysis, transient recording, and machinery diagnostics. Balance sampling rate, resolution, and channel count against system capabilities.
