1. A technique for determining a bit error rate comprising:
receiving a digital signal;
resetting an error counter and starting a time counter;
detecting errors in said digital signal, wherein said error counter is updated for each error detected;
determining when said errors counter reaches a predetermined threshold;
stopping the time counter when said errors counter reaches said predetermined threshold; and
calculating a bit error rate based upon said predetermined threshold and a value of the time counter.
