Apparatus and method for displaying a waveform at high rate with a large aquisition memory |
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 (104). A user sets a time interval of user's interest when viewing a signal under test and sets trigger criteria through a user interface (300,400). An ADC (103) converts the signal under test into digital data that is stored in a large acquisition memory. A trigger unit (105) detects and produces trigger events, based on a trigger, as trigger event information during one acquisition process. A trigger event eliminator (116) 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 (128) as the trigger event information. A control unit (200) 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 (302). |
