We are reading samples from the NI 6132 board through the DAQmx interface in continues mode, i.e.
inputTask.Timing.ConfigureSampleClock(string.Empty, 1000000, SampleClockActiveEdge.Falling, SampleQuantityMode.ContinuousSamples, 1000);
We successfully read analog waveform records in call back function, and we look at samples - they are correct.
We need to know the moment when start trigger has happened for each acquisition.
The data is read to the variable
AnalogWaveform<double> awf = ...;
and we do the following
if(awf.IsPrecisionTimingInitialized)
{
InitialXTimeSeconds = awf.PrecisionTiming.StartTime.WholeSeconds;
InitialXTimeFraction = awf.PrecisionTiming.StartTime.FractionalSeconds;
}
The problem: InitialXTimeSeconds and InitialXTimeFraction are the same for all records and equal to the start of the task, i.e. time of the acquisition of the first record. What is wrong?
