摘要： A system and method for testing the jitter tolerance and signal attenuation tolerance of an optoelectronic device is disclosed. The system includes a generation circuit, delay circuit and comparison circuitry. A first sequence of bits is generated, delayed, and sent to the optoelectronic device. The optoelectronic device receives the bits and retransmits them as a second sequence to the comparison circuitry, which compares the two bit sequences to determine a bit error rate. The bit error rate is then used to determine the jitter tolerance and, in an alternate embodiment, the signal attenuation tolerance of the optoelectronic device being tested.

摘要： Systems and methods are disclosed measuring the turn-on and turn-off times of an optoelectronic transceiver's transmitter circuitry. The method includes generating a two bit sequences from separate bit sequence generators using the same controlling pattern. The first bit sequence is transmitted through an optoelectronic device and compared with corresponding bit groups in the second bit sequence. The optoelectronic device is disabled and a count of compared bit groups is kept until the comparison indicates that the optoelectronic device is completely off. Using the count and one or more of the bit groups, a turn-off time is calculated. Alternatively, the method is used to calculate a turn-on time. The optoelectronic device is enabled and a count is kept from the time the device is enabled to when the comparison of the corresponding bit groups indicates that the optoelectronic device is completely on.

摘要： Systems and methods to measure signal propagation delay through objects. The system includes a controller, a single shot pulse generator, a first pulse/edge former, a multiplexer/demultiplexer, a second pulse/edge former, a timer, and a counter. The controller initializes the system, the clock and the counter. A pulse is sent from the single shot pulse generator to the first pulse/edge former. The pulse is propagated through the first pulse/edge former to the multiplexer, through a device under test, to the demultiplexer, and to the second pulse/edge former. The second pulse edge generator provides the pulse to the counter, which counts a predetermined number of pulses, and the clock, which measures the amount of time the counter counts the pulses. The propagation delay of the device under test is then calculated based on the counted number of pulses and the elapsed time measured by the clock.
