a basic question about hardware-timed sampling mode

[feilong]

Hello All,

After read many articles about single-point hardware-timed mode, I still have a basic question though.

Compare with continuously sampling mode with buffer set to 1, This single-point hardware-timed mode doesn't provide a buffer. So what's the benefit and difference? Does it mean no buffer mean the DAQmx Read vi return faster?

I actually use this mode for a long time but never thought about this question seriously.

thanks

Feilong,

Hardware-Timed Single Point Sample Mode is meant for use on real time systems. You would use this while knowing the amount of time it takes a loop to execute. Here is a good article with some benchmarks using single-point.
