摘要： A method and apparatus for measuring characteristics in an electromagnetic or optical system. A modulation signal is provided to a device under test to provide a first signal and to a reference device which provides a second signal, and a time domain optical analyzer measures the transitions of the first signal and the transitions of the second signal to determine characteristics of the device under test. In one embodiment, the characteristics of the reference device are determined with a modulated light source having two or more known wavelengths that provides a first signal, and a second signal is provided to a reference device to create a third signal. A time domain optical analyzer measures the transitions of the first signal and the transitions of the third signal for two or more wavelengths to determine reference device signal delay time characteristics as a function of wavelength.

摘要： A method and system for removing the effect of intersymbol interference (ISI) from a data record indicating times of logic level transitions exhibited by a data signal that has been distorted by ISI exhibited by a system having a particular step response may perform the following acts. The data record may be received, and a transition from within the data may be selected record for removal of ISI. Preceding transitions within the data record are then inspected. A time defect is obtained, based at least in part upon the inspected preceding transitions. Finally, the data record is adjusted, based upon the time defect, to indicate a new time of transition for the selected transition, thereby removing the effect of ISI for the selected transition.

摘要： A system for multichannel analysis and testing is provided. The analysis system includes a modulated electromagnetic source having two or more wavelengths or frequency, a multichannel system having a plurality of signals, coupled to the modulated electromagnetic source, a switch for selecting more than one of the signals, and a time domain analyzer for measuring delay between one of the signals and more than one of the other signals to determine system characteristics. The time domain analyzer measures delays between the transitions of a first signal, measures delay between the transition of a first signal and the transition of each of many of the other signals for many signals, and then generates a matrix of the measurements. The matrix is analyzed to determine system characteristics.

摘要： A method for measuring a bit error rate in a communication system that includes a transmitter, a medium, and a receiver. The method may include identifying a plurality of causes of bit errors. For each cause, the communication system is measured to determine a corresponding probability density function. Each of the corresponding probability density functions is integrated over an interval representing a range in which the corresponding cause creates a bit error, thereby generating a plurality of integrated quantities. The integrated quantities are summed to arrive at a bit error rate for the communication system. An apparatus may be programmed to execute the foregoing method.
