JRys, Do any products sold by MCC contain latency information that I can reference? This kind of thing is obviously vital to any DAQ application intended for control so I would be surprised if none of the MCC products have this information. Apparently the latency due to the USB connection itself is only about 100 microseconds so if the latency is too great for my application it must be due to either the FIFO or something else about how the data is processed before being sent over the USB connection. I don't need to know its exact value but I do need to know if it is vastly greater than the latency imposed by the USB connection itself.

Thank you! I found this quite helpful. JRys, I intend to use the DAQ only for analog inputs. The outputs will be provided by another device. Do you concur with Mark's analysis of the latency for analog inputs? Is there a way for me to control the FIFO so that it empties more frequently?

I am interested in a real-time control application that needs to stream data in with a latency below 1ms. Does the USB-1808X offer this capability? Thanks!
