1. A method of measuring the error rate of an optical transmission system transmitting a signal, said method comprisesdetecting said signal, asynchronously sampling said signal at a frequency independent of a bit rate of said signal to obtain K samples of said signal at respective limes t1, to tK where K is an integer greater than or equal to 2, computing a bit time of said signal, computing an diagram of said signal using the computed bit time of said signal, and computing an error rate of said signal.
