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： An improved hold-off algorithm that assures that all data associated with all trigger events in a data signal are displayed uses a designated interval starting with a first trigger event to determine whether any subsequent trigger events occurred within the designated interval. A first display frame is drawn based upon the first trigger event. A next display frame is drawn based either on a next trigger event that occurs outside the designated interval, or based on the last trigger event that occurred within the designated interval. In the latter case the two display frames provide an overlap to assure that no data related to the trigger events is lost on the display.
摘要翻译：确保显示与数据信号中的所有触发事件相关联的所有数据的改进的保留算法使用从第一触发事件开始的指定间隔来确定在指定间隔内是否发生任何后续触发事件。基于第一触发事件绘制第一显示帧。基于在指定间隔之外发生的下一个触发事件，或者基于在指定间隔内发生的最后一个触发事件来绘制下一个显示帧。在后一种情况下，两个显示帧提供重叠，以确保在显示器上没有与触发事件有关的数据丢失。

摘要： A test and measurement instrument according to an embodiment of the present invention converts digital data that represents an analog input signal into a time-domain bitmap, and then compares a region of that time-domain bitmap to a density threshold. When the density value violates the density threshold, a trigger signal is generated that causes digital data to be stored into a memory.

摘要： A test and measurement instrument and method for providing post-acquisition trigger control and presentation of associated waveforms on a display. An electrical signal under test is sampled and digitized, and stored in an acquisition memory as a data record. A display device draws a waveform associated with the signal under test. After the acquisition of the digital samples is stopped, a user selects trigger criteria using trigger controls such as a trigger level control. A trigger circuit detects a post-acquisition trigger event in the data record based on the trigger criteria causing an automatic adjustment of the waveform to conform to a time of the post-acquisition trigger event. One or more configurable trigger controls can be used to adjust a display of post-acquisition trigger events and waveforms. Upon resumption of the live-acquisition of data, the live waveform conforms to the newly selected trigger criteria as previewed during the post-acquisition mode.

摘要： Pre-trigger and post-trigger acquisition for a no dead time acquisition system, where the data being displayed does not include a related trigger event, has a variable record length buffer having a maximum record length equal to a maximum desired pre-trigger interval, and has a trigger FIFO and timer for delaying the related trigger event. The record length of the buffer is determined by the desired pre-trigger interval, and fast rasterizers access the oldest data that encompasses the desired pre-trigger data. A first trigger event in the trigger signal may be delayed by a desired post-trigger interval before the fast rasterizers begin drawing the waveform data that encompasses the desired post-trigger data.
