Many Factors, and What you Prioritize

Ease of Use - Set-up time, and first time to measurement Channel Count and Synchronization - How many channels?

What must be synchronized?

Channel Distribution - How far will your measurements befrom the PC? Waveform Speeds Bandwidth must support required data

throughput

Single-point Loop Rates - Both determinism and latency


17/92

Depends on Your Application

Casual Data Monitoring or LoggingExample: Occasional benchtop measurements

Distributed MonitoringExample: Bridge health monitoring

Single-Point Read/WriteExample: PID Control

Dedicated Bandwidth Per DeviceAdditional Advantage for High Channel Count Applies to PCIExpressand PXIExpress


24/92

24

How Much Bandwidth is Enough?

Bandwidth needed = # of channels * bits of resolution(bits) * sampling rate (S/s) / 8

Check which buses allow for your needed bandwidth,assuming 30% overhead

If you need more bandwidth than a single PCIe slotprovides, consider adding devices

Consider the Role of Remote Communication

For a system where you need to control the hardware from a distance:Consider LAN or WiFi as the bus

For any system where you would like to share the data across locations:Choose the bus thats best for the local connection between the host PC and DAQ hardwareConsider LAN as a networking tool for sharing data
