I created a simple VI to measure the elapsed time, which the serial communication protocol needs to transfer several characters.
But if I do theoretical calculations, also with different baud rates in the sub-VI conf s-port, the theoretical results differ a lot from the measured results.
I also observed, by increasing the number of transferred characters one by one, the elapsed time decreases or increases.
I attached the VI. Can anybody tell me, if I am doing completely wrong and maybe there is a better and more precise method to measure the transfer time of a serial communication.
Thanks a lot.
