I'm trying to measure the period of a very slow frequency (0.083 Hz) coming into my DAQ(6009).
However it comes with "Error -20309 occurred at "NI_MAPro.lvlib:Pulse Measurements 1 chan.vi:2" when called from "NI_MAPro.lvlib:Pulse Measurements N chan.vi:1" (waveform index 0 of 1)".
The DAQ is capturing method is set to "on demand" however I have also tried various (frequency + buffer) such as 10k by 2k.
but it still comes up with the error.
I know why it comes up with this error but don't know how to fix it.
I have attached the vi (the simulate signal is replicating my DAQ)
