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.

Method of generating metadata from acquired signals for search, filtering, and machine learning inputs

A method of synchronizing tasks in a test and measurement system, includes receiving, at a client in the system, a task input, receiving, at a job manager running on a first device processor in the system, a call from the client to create a job associated with the task, returning to the client an action containing at least one job code block associated with the job, receiving a call for the action, executing the at least one job code block by at least one processor in the system, determining that the job has completed, and completing the task. A system of devices including at least one test and measurement device and a device controller, the device controller having at least one user input, a device controller processor configured to execute instructions, and at least one memory to store the data and to store instructions in the form of executable code, wherein the code causes the device controller processor to receive an input from a client, the input identifying a task, create a job associated with the task, return to the client an action containing at least one job code block associated with the task, receive a call for the action, determine that the job has completed, and notify the client that the job has completed.

Multi-instrument behavior synchronization using jobs and milestones

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.

Automatic detection of logical path segments in a measurement population

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.

Selective extraction of network link training information

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.

Hardware trigger generation from a declarative protocol description

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.

Serial bit stream regular expression with states

A test-and-measurement instrument is described. The test-and-measurement instrument can store a state machine. As the state machine is used to analyze a bit stream, breadcrumbs can be saved from states in a memory of the state machine. The breadcrumbs can then be used to analyze the operation of the state machine.

Deriving hardware acceleration of decoding from a declarative protocol description

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.

Methods and systems for aiding the analysis of a signal

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.

Protocol sensitive visual navigation apparatus

A test and measurement instrument including a user interface; and a controller is described. The controller is configured to receive a serial bit stream; apply a regular expression to the serial bit stream; and present acquired data, or other data, through the user interface in response to the application of the regular expression to the serial bit stream.

A method of analysis of long record length data using mark duration includes displaying together with a portion of the long record length data each mark that identifies a specified feature of interest together with the mark duration. Associated with the mark may be text identifying the feature of interest, measurement values associated with the duration of the mark, or a combination thereof. Multiple sets of marks may be generated for the long record length data, which sets may be combined to generate new marks with duration. The marks also may be filtered to further refine the marks to be displayed according to user specified criteria. In this way analysis of long record length data representing an acquired signal may be readily automated so a user may move from one interesting event to another without having to pan through the long record length data.

Mark extension for analysis of long record length data

The method of processing waveform data from one or more channels using a test and measurement instrument, such as an oscilloscope, is described in which waveform data is collected from a DUT; defining a context is defined by instructing the instrument to obtain the focus of each waveform datum having a first user-defined attribute; defining a selection criteria by instructing the instrument to obtain the focus of each waveform datum having both a first user-defined attribute and a second user-defined attribute; and defining an action by instructing the instrument to perform an operation responsive to finding at least one waveform datum having both the first user-defined attribute and the second user-defined attribute.

Method of processing waveform data from one or more channels using a test and measurement instrument

A simple, integrated control for pan and zoom of a display of data represented by a very long data record is in the form of a control knob having an outer ring for controlling pan and an inner knob for controlling a zoom factor. A zoom function is turned ON either by turning the inner knob (setting the zoom factor to a default value) or by (i) pressing an adjacent zoom or pan button or (ii) turning the outer ring (setting the zoom factor to a prior value when the zoom function was turned OFF). The zoom function may be turned OFF by turning the inner knob to set the zoom factor to 1&#xd7; or by pressing the zoom button. The outer ring has individual positions divided into two groups: one group for controlling pan rate within a zoom window displaying a portion of the very long data record defined by a zoom box within a main window displaying the very long data record; and the other group for controlling pan rate of the zoom box within the main window for rapid movement from one end of the record to another.

Simple integrated control for zoom/pan functions

A test and measurement instrument includes a memory configured to store a digitized signal, a display configured to display the digitized signal, a mark interface configured to generate a mark creation signal, a processor coupled to the memory, the display, and the mark interface. The processor is configured to identify a feature of the digitized signal and create a mark indicating the feature and the digitized signal in response to the mark creation signal.
