I am using LV 8 on W2K. I am making a 1ms wide pulse with CTR0 on a PXI-6259. If I put a DAQmx Wait Until Done after the pulse generation and before clearing the Task, it takes 100ms ;to return from DAQmx Wait Until Done. If I try to generate a second pulse as soon as possible after the first, I can't get them any closer than 100ms or so. I remove the DAQmx Wait Until Done, generate a pulse, clear the task, generate another pulse immediately thereafter, and it works. No errors, so the task must have finished OK. Any idea why DAQmx Wait Until Done takes so long to return? I have seen the same thing by starting the task and then polling DAQmx Is Task Done?.Regards, DaveT

DAQmx Wait Until Done takes an extra 100ms

What is the max polling rate these days? I think I might be cutting off the end of my generated waveform when I call stop task but Wait Until Done slows everything down considerably.
