    摘要: 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.

    摘要: A method of indicating and manipulating a zoom region of a waveform being displayed includes a zoom region indicator. The zoom region indicator has an associated marker that spans the zoom region but is never less than a minimum span to allow ease of identifying or locating the zoom region on the displayed waveform. Manipulating the associated marker with a pointer device causes the zoom region to move accordingly along the displayed waveform. The portion of the displayed waveform that is within the zoom region is displayed as a zoomed waveform on the display.

    摘要: An encoded serial data bit error analyzer captures the actual waveform of an encoded serial data stream associated with a bit error so that a user may readily validate the cause of the bit error. An encoded serial data stream decoder in the analyzer is modified to provide a signal for a trigger system when a characteristic of a bit error failure is detected. A power splitter produces a pair of incident encoded serial data streams from a programmable test signal, one of which is input to a device under test and the other is input to the analyzer. A re-transmitted encoded serial data stream from the device under test is input to another channel of the analyzer. The encoded serial data stream decoder provides an “error detected” output when a condition occurs in the re-transmitted encoded serial data stream indicative of a bit error. The “error detected” output is used as a trigger signal to capture the incident and re-transmitted encoded serial data waveforms surrounding the detected bit error.
