Hi all,
I tried to output violtages triggered by an external TTL with a very low frequency (below 1 Hz).The voltage serises is a real-time made 1-D array or read from a predefined ASCII file. I want it do it that the analog output will change to the next voltage in the array when a rising edge of the trigger source comes .But I always get the error message "DAC conversion attempted before data to be converted was available" when I try to run it.
Is it because the trigger frequency too low? Can anybody help me?Thanks.
