Data Acquisition Device (DAQ)  Function:  Gathers information in an automated fashion from analog and digital measurement sources.  Uses a combination of PC-based measurement hardware and software to provide a flexible, user- defined measurement system.  Set up

Data Acquisition Device (DAQ)  Model: NI PCI-6533 (DIO-32HS)  Specifications: 32 digital I/O lines 8, 16, 32-bit transfer. Start and Stop triggering Up to 5MHz clock rate PCI bus

Data Acquisition Device (DAQ)  Why we choose NI PCI-6533 Pattern I/O  Converts analog signal to digital patterns signal Start and Stop Trigger Clock Rate of 5MHz – Sampling rate of 200ns Noise rejecting Cheapest DAQ model that meets these requirements

What We are Going to Do  Turn in specifications and schedule to client  Get C++ software  Continue research
