摘要： A signal processing system may compensate for the relative phase difference between multiple frequency bands so that the combination of the bands is constructive throughout a substantial portion of the band overlap or crossover region. In one embodiment, a signal combining system may include a comparator for determining a relative phase difference between the two signals within a predefined crossover region, a phase adjusting element for adjusting a phase of one of the two signals; and a combiner for combining the phase-adjusted signal and the other of the two signals.

摘要： A method for improving bandwidth of an oscilloscope involves, in preferred embodiments, the use of frequency up-conversion and down-conversion techniques. In an illustrative embodiment the technique involves separating an input signal into a high frequency content and a low frequency content, down-converting the high frequency content in the analog domain so that it may be processed by the oscilloscope's analog front end, digitizing the low frequency content and the down-converted high frequency content, and forming a digital representation of the received analog signal from the digitized low frequency content and high frequency content.

摘要： A method and apparatus for determining a trigger in a test and measurement apparatus are provided. The method includes the steps of indicating one or more anomalies to be found, loading a first trigger configuration to the test and measurement apparatus and determining for a first predetermined time period whether an input signal generates a trigger related to one or more of the one or more anomalies. A second trigger configuration is loaded to the test and measurement apparatus upon the conclusion of the first predetermined time, and for a second predetermined time it is determined whether the input signal generates a trigger related to one or more of the one or more anomalies.

摘要： A method, computer program, and apparatus for compensating for group delay. The method comprises the steps of generating a raw step response of a system, differentiating the raw step response to generate an impulse response of the system, windowing the impulse response and taking a Fast Fourier Transform (FFT) of the windowed impulse response to generate a frequency response of the system. A phase response of the system is then calculated from the frequency response, and an IFFT Group Delay filter is defined in accordance with the phase response of the system. Finally, the IFFT Group Delay filter is applied to the raw step response.

摘要： A method for improving bandwidth of an oscilloscope involves, in preferred embodiments, use of frequency up-conversion and down-conversion techniques to achieve a system bandwidth that significantly exceeds the bandwidth attainable through interleaving alone. In an illustrative embodiment the technique involves separating an input signal into a high frequency content and a low frequency content, down-converting the high frequency content in the analog domain so that it may be processed by the oscilloscope's analog front end, digitizing the low frequency content and the down-converted high frequency content, and forming a digital representation of the received analog signal from the digitized low frequency content and high frequency content. In this manner preferred embodiments achieve the significant advantage that bandwidth may be enhanced beyond the limits associated with interleaving and the state of the art in amplifier and ADC design.
