USB 6008 AI and AO

[star-123]

Hi Friends,

I have a problem about usb 6008. Sample rate and number of sample can not determined by using sample clock function when analog output is used. How is determined these parameters for analog output? Also, there is a time difference between analog input signal and analog output signal. What is the reason of the time difference? How can I solve it?

Sincerely,

Hi 1085,

I have a problem about usb 6008.

The problem is: you didn't read the manual of the USB6008 or the USB6008 specs… 😄

How is determined these parameters for analog output?

The sample rate is determined by the iteration time of your loop used to output the AO values. And by the comments in the manual!

there is a time difference between analog input signal and analog output signal. What is the reason of the time difference?

The reason probably is your VI used to read AI and output AO values…

How can I solve it?

Attach your VI to get reasonable comments…
