Hello Andrew,
I’m sorry, I’m not explaning my question very well.
I want to start collecting signals at the same time.
Last week, I write code to collect the same signal with two BB60C devices using external triggers(second pulse).The sample rate is 625000.
I think trigger location is the same moment, but it is not.
I draw the IQ image with MATLAB. Obviously, it is not the same moment two sets fo data collection(the difference between the two trigger location for more than 800ns * 100 = 80000ns).
So I wonder how many nanoseconds precision can reach when i use external trigger?
I’m looking forward to your answer.
