Abstract: A method of testing a data transmission and reception system comprises sending a test signal from a transmitter (14) of the system to a receiver (12) of the system, and analyzing the received signal. A duty cycle relationship is varied between the test signal and the timing signal used by the receiver of the system, and the effect of the duty cycle variation is analyzed. Varying the duty cycle relationship provides duty cycle distortion (DCD), and this can be considered as a form of embedded jitter insertion. This type of jitter can be measured relatively easily.
