My guess is that your card buffers the data. Given your low sampling rate of 1 Hz the acquisition sequence is probably over before the buffer has grown full enough for the card to send you the data. In this case adding TRIG_WAKE_EOS to the cmd flags may help to get the data earlier. > Thanks in advance, > > Marcel HTH, Jan
