Hi, I am using a USB 6009 DAQ to do some tests for a future system.Actually I succed to tigg the Analg channel 1 with a ext trigg.I have sevral problems:1) the jiter of my signal is around 5 ns and as I have to measure the max of gaussian form I cann't do it! is there any solutions to stabilize that?2) I tried the measure the trigger latency and I found that it is around 20 us (the sample rate is 50kHz). I guess that the internal clock drive the triggering latency. Because on another board that the sample rate is also 50 kHZ and I had the same latency.I would like to know if it is true or I am doing somthing wrong.3)I would also to know where is it possible to find this kind of information if I want to buy another board with better performance.ThanksAnouch
