摘要： A digital storage oscilloscope employs an improved edge triggering circuit that discards some of trigger events when it determines that there are many more trigger events than the oscilloscope can use. The determination is made in response to detection of a characteristic of the signal that indicates a repetitive nature of a complex signal. Certain trigger events are selected to be acted upon, and others are discarded, in response to the determination. The circuitry dynamically reacts to changes in the input signal in response to detection of different criteria for a characteristic of repetition as the input signal changes.

摘要： A waveform display apparatus and method displays one or more waveforms of a signal under test at high throughput while acquiring digital data of the signal under test in a large acquisition memory. A user sets a time interval of user's interest when viewing a signal under test and sets trigger criteria through a user interface. An ADC converts the signal under test into digital data that is stored in a large acquisition memory. A trigger unit detects and produces trigger events, based on a trigger, as trigger event information during one acquisition process. A trigger event eliminator may discard some of the trigger events based on pre-trigger and post-conditions set through the interface by a user. The trigger events are recorded in a trigger list as the trigger event information. A control unit locates the digital data in the acquisition memory corresponding to the trigger events in the trigger list and displays a waveform associated with the trigger event for the time interval on a display device.
摘要翻译：波形显示装置和方法以高吞吐量显示被测信号的一个或多个波形，同时在大的采集存储器中获取待测信号的数字数据。用户在查看被测信号时设置用户兴趣的时间间隔，并通过用户界面设置触发条件。 ADC将被测信号转换为存储在大型采集存储器中的数字数据。触发单元在一次采集过程中，根据触发信号检测并产生触发事件作为触发事件信息。触发事件消除器可以基于用户通过接口设置的预触发和后置条件来丢弃一些触发事件。触发事件记录在触发列表中作为触发事件信息。控制单元将对应于触发列表中的触发事件的采集存储器中的数字数据定位在显示设备上，并且在时间间隔上显示与触发事件相关联的波形。
