As I know, there are two ways to AO signals using 4461 which depends on the parameters of DAQmx Timing.vi,sample clock and use waveform.
1.Sample clock: when adopting this way, I'd like to know which parameters the quality of waveform depends on. the sample clock (update rates)?,the number of samples per period? the cycles? And I also want to know how I set up these paremeters when generating waveform at different frequencies. For example, when generating a sine wave of 1KHz,I can set the sample clock to 100KHz,and set the number of samples per period to 100S, set the cycles to 1.Also, another way is, sample clock to 200KHz,number of samples per period to 200S,cycles to 2.Then, what is the difference between the two ways?
2.Use waveform: we can use Waveform Generatition Buffer.vi before DAQmx Timing.vi to set up the parameters of the desired waveform.Then what is the difference between the two ways of AO , and which is better?
Thanks a lot!
