A protocol designer for a test and measurement instrument, comprising an input to receive a signal, a memory configured to store the signal, an author configured to generate protocol definitions based on a user input, a debugger configured to output textual and visual decode results based on the protocol definitions and the signal, and a deployer configured to output a compiled protocol definition file to the test and measurement instrument.

Integrated development environment for protocol design, evaluation and debugging

Disclosed herein are systems and methods for converting physical input signals into bitstreams using syntax trees regardless of the physical input signal's protocol. Using declarative language definitions within a protocol declaration, a test and measurement system can compile a syntax tree that automatically translates the input data into a proper bitstream output. The declarative language definitions within the protocol declaration allow custom or standard protocol rules to be written for multiple or arbitrary input protocols without writing unsafe functions, having to access memory, or debugging more complex language codes.

System and method for bitstream decoding with compiler-generated syntax trees

A logic analyzer that performs analog-type measurements on digital data includes circuitry in its acquisition system that is programmable to search through acquired data to detect analog-type signal characteristics. In a first embodiment, the logic analyzer includes a graphical user interface employing a drag-and-drop operation to apply one or more selected analog-type measurements to selected portions of the digital data record. In a second embodiment, a user may designate a particular waveform or data listing by means of a mouse-click. Each of the choices of analog-type measurements can be represented by an icon, or text, or both icon and text. Some of the analog-type measurements, among others, are pulse width, duty cycle, period, frequency, period jitter, and cycle-to-cycle jitter
