Hey, I am making a function Generator in LABVIEW and by using the device myDAQ, I want to get Analog output. My input frequency is in the range of 10MHz. When I run the code, a message shows that Error-200018 occured at DAQmx Write (Analog 1D Wfm Nchan Nsamp).
Possible reason shows that :
Decrease the output Frequency to increase the period between DAC conversions, or reduce the size of your output Buffer in order to write data more often.
I dont want to decrease the output frequency, So how can this problem be fixed? is there any other solution? Can it be solved by changing buffer Size, if yes, then How can Buffer size be changed?

Hi AhmadAK,
Based on the specifications of the myDAQ, it only has analog input/output sampling rate of a maximum of 200kHz. You won't be able to read or generate a signal at 10MHz. Currently what sampling rate is your analog output task setup as?
