Abstract:
A testing device for testing dynamic characteristics of an electronic component or circuit using serial transmissions, the component or circuit including a multiplexing device and a demultiplexing device for implementing a serial link in the component or circuit, said testing device comprising:a transmitter transmitting binary signals to be multiplexed to the multiplexing device, a data processing circuit being coupled to the multiplexing device; a receiver receiving the multiplexed binary signals from the demultiplexing device, the data processing circuit also being coupled to the demultiplexing device; a link selectively providing a coupling between the transmitter and the receiver, the link including a switch; and a clock generator delivering a first clock signal and a second clock signal, which has a different frequency than the first clock signal, wherein the first clock signal is supplied to the transmitter and the second clock signal is supplied to the receiver.
