Using a USB-6215 board to generate a sine wave (N periods, Repeated signal) on AO0 and AO1 pins I found a strange problem:
when the sample rate is high (more than 30 MHz, more or less) everything works fine only if the block size is more than 1000 samples.
If I use small blocks (120 samples, for example) the signal is generated only for a while, then I can't see the waveform anymore without errors.
I noticed this behavior with LabVIEW Signalexpress 2011 and DAQmx 9.3.5
