Hi, I use the fujnction WriteAnalogF64 to write 100 samples in an analog port for my SCB-68 (NI) card, I have an multimeter to read the output for this port, it works great (no delay) under the TEST window of NIDAQ-MX task creation, in my code I call the created task, and every .120 sec the function WriteAnalogF64 is executed, but has a big delay..... i dont know what could procuce it....
thanks.
