    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: A test and measurement apparatus, system, and method for synchronizing an acquisition or triggering system to a specific burst of interest. The subject apparatus and method triggers on varying energy content of a signal qualified by time in the presence of high-frequency input signal bursts, by using an adjustable pulse width envelope detector, disposed in the signal path of the trigger circuitry, as a digital rectifier or to otherwise process and extract an envelope signal. An RF envelope probe having an analog envelope detector among other suitable components is disclosed. A method is implemented for isolating an interval of interest in a signal under test. An envelope detector circuit produces an envelope signal from the signal. Trigger circuitry receives the envelope signal from the envelope detector, and isolates the interval of interesting in the signal under test using the envelope signal.

    Abstract: This disclosure relates generally to test and measurement instruments structured to detect that a series of events occurred, and structured to generate a trigger signal in response to detecting that a final event in the series of events occurred. The trigger may be generated based on a timeout signal, or based on another event, trigger, or signal. Stored data in the acquisition memory may be marked relative to the detection of the final event. An external forced timeout signal may control which in a series of events is marked as a final event. The triggering on final event may be enabled after another trigger is satisfied, and may be used as one of many different types of triggers.

    Abstract: A test and measurement instrument including an input port configured to receive an input signal. One or more divider circuits, coupled to the input port, employ a plurality of divide ratios such that each divide ratio scales an event signal indicating events in the input signal by a predetermined integer value. A control system is also included. The control system is configured to iteratively determine an estimated signal frequency of the event signal, and automatically select a divide ratio for the event signal based on the estimated signal frequency. The instrument may also include one or more counters to count triggers in the event signal subsequent to application of the divide ratio. The instrument may also employ frequency hysteresis to prevent chatter in divide ratio selection.

    Abstract: An apparatus and method that captures a complete history of serial network Link Training negotiations by continuously monitoring multiple analog signals representing both sides of full duplex lanes in real-time by pattern matching the Link Training Frame Marker and the subsequent negotiation request/response data values. The apparatus and method compare the digitized version of the incoming signal against a nominal pattern at the start to find the Frame Markers and Control Channel data, storing only those Control Channel data values that do not match the current compare pattern, and further by updating the current compare pattern to the new pattern just received, so that only the transitions in the data values are stored, thereby vastly reducing the amount of data presented to the user, but nonetheless retaining the complete substantive history of the Link Training negotiations.
