The National Instruments PCI-6033E is a multifunction data acquisition board designed for PCI bus computers. It delivers 16-bit analog input resolution across up to 64 single-ended or 32 differential channels at 100 kS/s per channel, making it well-suited for laboratory automation, design verification, and manufacturing test environments. The board integrates two analog outputs, 8 digital I/O lines, and dual 24-bit counters alongside the DAQ-STC system timing controller for precise signal synchronization.
