Abstract: A computing device includes a port to allow the computing device to connect to a network, and one or more processors, the one or more processors configured to execute code to cause the one or more processors to determine that a new waveform has been added to a repository connected to the computing device, perform a set of measurements on the new waveform, attach results from the measurements to the new waveform as metadata, and store the new waveform and attached metadata to the repository. A method of managing waveform data includes determining that a new waveform has been added to a repository, performing a set of measurements on the new waveform, attaching results from the measurements to the new waveform as metadata, and storing the new waveform and attached metadata to the repository.

Abstract: A test and measurement instrument, including a memory configured to store a waveform data record; one or more processors, and a display. The one or more processors are configured to receive the waveform data record, determine a measurement value and location for a plurality of occurrences of a measurement event in the waveform data record, detect one or more logical path segments in the plurality of occurrences, and generating a visual representation of each measurement value and overlaying each of the visual representations of each measurement value. The visual representations of each measurement value and/or the one or more logical path segments may be displayed on the display.

Abstract: An oscilloscope includes an input port to receive an input signal, a trigger system coupled to the input port and operable to generate a trigger signal in response to detecting a trigger event in the input signal, the trigger system includes at least one finite state machine, and a snippet compiler configured to accept one or more Declarative Trigger Language (DTL) code snippets as an input, compile the one or more DTL code snippets into one or more state machine op codes, and output the one or more state machine op codes. The trigger system uses the one or more state machine op codes to configure the at least one finite state machine.

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.

Abstract: A test-and-measurement instrument is described. A state machine, corresponding to a regular expression, can be stored in the test-and-measurement instrument. The state machine can be modified to reflect a trigger condition received from a user. The modified state machine can then be used to invoke a trigger when the condition is met in the bits of a bit stream.

Abstract: A test and measurement instrument includes a user interface and a controller. The controller is configured to receive a serial bit stream and apply a logic to the serial bit stream to identify states within the serial bit stream. The result of applying the logic to the serial bit stream is a combined state/bit stream. A regular expression can be applied to the combined state/bit stream: the regular expression can include state information. The controller is also configured to present output data through the user interface in response to the application of the regular expression to the combined state/bit stream.

Abstract: Method and related systems are described for navigating through information related to the status of one or more layers of a signal, such as a serial or parallel bus. Information may be displayed by selecting fields within a visual depicted on an oscilloscope or similar measuring instrument. By selecting particular fields, and indicators, different aspects of a layer may be analyzed without the need to have extensive knowledge of the operation of the measuring instrument.

Abstract: Embodiments of this invention include a protocol sensitive visual navigation apparatus, and associated methods, for navigating and relating different protocol levels of a protocol. A test and measurement instrument can include the protocol sensitive visual navigation apparatus, which can facilitate analyzing, searching, and measuring various aspects of the different protocol layers and cross-correlating items from one protocol layer to another protocol layer. The type and characteristics of the analysis is informed by a selected protocol layer. Physical layer signals or events can be correlated to protocol level information, thereby increasing an understanding of the overall protocol and associated protocol layers and events.
