Abstract: A test and measurement instrument, including an input configured to receive a signal-under-test, a user input configured to accept a first trigger event and a second trigger event from a user, a first trigger decoder configured to trigger on an occurrence of the first trigger event and generate a first trigger signal, a second trigger decoder configured to trigger on an occurrence of the second trigger event occurring after the first trigger event and generate a second trigger signal, and an acquisition system configured to acquire the signal-under-test in response to the first trigger signal and store the acquired signal-under-test based on whether the second trigger signal validates or invalidates the first trigger signal.

Abstract translation: 一种测试和测量仪器，包括被配置为接收待测信号的输入，被配置为接受来自用户的第一触发事件和第二触发事件的用户输入;第一触发解码器，被配置为在发生 第一触发事件并产生第一触发信号，第二触发解码器被配置为在发生第一触发事件之后发生的第二触发事件触发并产生第二触发信号，并且获取系统被配置为获取第一触发事件， 根据所述第一触发信号进行测试，并且基于所述第二触发信号是否验证所述第一触发信号或使所述第一触发信号无效来存储所获取的待测信号。

Abstract: A test and measurement instrument, such as an oscilloscope, including one or more ports to receive one or more signals from a device under test, a trigger enable logic circuit configured to output a trigger enabled signal when a trigger enable event occurs within the one or more signals, the trigger enable event being a real-time event of the one or more signals, one or more trigger logic circuits configured to generate a plurality of trigger signals when the trigger enable signal is received, each trigger signal being generated when a trigger event occurs within one of the one or more signals, and an acquisition circuit configured to acquire and store data in a memory in response to each of the trigger signals.
