  • Patent number: 8532953
    Abstract: A method and apparatus for determining a trigger in a test and measurement apparatus are provided. The method comprises the steps of loading a first trigger configuration to a first trigger element of the test and measurement apparatus and loading a second trigger configuration to a second trigger element of the test and measurement apparatus so that these trigger elements operate substantially simultaneously, It is then determined whether the input signal generates a trigger in accordance with the one or more trigger configurations.
    Type: Grant

  • Patent number: 8386208
    Abstract: 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.

  • Patent number: 7957938
    Abstract: A method of digitizing an analog signal is provided, comprising the steps of separating the analog signal spanning a frequency range into a plurality of frequency bands, and then translating at least one of the signals to a lower frequency band in accordance with a local oscillator and digitizing the at least one translated signal with digitizing elements having a frequency range less than the analog signal frequency range. A fixed relationship of the phase of the local oscillator and a repetitive signal generated in accordance with a writing to a circular buffer of the digitized representation of the at least one of the plurality of frequency bands is then defined. Signals corresponding to the other of the plurality of frequency bands are digitized and written to corresponding circular buffers. Finally, a digital representation of the analog signal is formed from the digitized signals.

  • Publication number: 20090093986
    Abstract: A method for correcting feed through signals for use with an oscilloscope employing Digital Bandwidth Interleaving is provided. The method comprises the steps of converting an original signal to a frequency other than an original frequency of the original signal, determining one or more feed through signals not converted with the original signal, providing an offsetting correction signal and combining the converted signal, the non-converted feed through signal, and the offsetting correction signal.

  • Publication number: 20090002213
    Abstract: A method of digitizing an analog signal is provided, comprising the steps of separating the analog signal spanning a frequency range into a plurality of frequency bands, each frequency band spanning a corresponding predefined frequency range, at least a portion of each of the plurality of corresponding frequency ranges not overlapping any other of the plurality of corresponding predefined frequency ranges and then translating at least one of the signals in the plurality of frequency bands to a lower frequency band in accordance with a local oscillator and digitizing the at least one translated signal with digitizing elements having a frequency range less than the analog signal frequency range. A fixed relationship of the phase of the local oscillator and a repetitive signal generated in accordance with a writing to a circular buffer of the digitized representation of the at least one of the plurality of frequency bands is then defined.
