How to define frequency for signal based on the pattern data written to DAQmx write?

[Thang Nguyen]

Hi,

I am working on writing the frequency pulse signal using digital output with correlated clock in CompactDAQ device. I found some examples about this already, But there is onething I don't understand is before start writing the signal out continuously, I have to define a pattern for my signal by writing an array of data to the DAQmx write. I don't understand about this. How to define the frequency and how to define the duty cycle? Could you please help me?

Best regards,
