I try to use Fastino output arbitrary waveform at 10KHz,but when I use set_dac and ‘for loop’ to generate ramp signal,as below 
I find that the minimum value of t_step(the delay after every set_dac) can only be 2*us, otherwise I will receive an overflow error. In that case, I can only have 50 data point in every period to edit my waveform, which is not enough.
How can I solve this problem?
I would be very grateful if you could reply to me.
thanks,
Z
