• Serial digital data extraction to an analog value (serial DAC) with waveform graphs
• Eye Diagrams with failure location

Triggering on the complex FlexRay protocol is made easy. Set up a simple TSS (Start) symbol trigger with a single button press or trigger on any part of a FlexRay frame including ID, Cycle Count, Cycle Repetition Factor, and Frame Qualifier. FlexRay defined Symbols and Errors can also be incorporated into the trigger making it as simple or advanced as necessary. Conditional triggering can be set to trigger on any range of Frame IDs or Cycles.

A transparent overlay with color-coding for specific portions of each protocol and the entire message frame makes it easy to understand your serial data information. Unlike other solutions, with protocol decode information away from the signal, our solution correlates the waveform and the protocol decode directly on the display. As the acquisition length is expanded or shortened, the decode overlay will adjust to show you just the right amount of information.

Turn the oscilloscope into a protocol analyzer with a tabular display of decoded information. Customize the table to show only the data of interest and touch a message in the table to automatically zoom to it and display it on the screen. Export the table for offline analysis. Up to four different decoded signals of any type may be simultaneously displayed in the table.

Quickly validate cause and effect with automated timing measurements to or from an analog signal or another serial message. Make multiple measurements in a single long acquisition to quickly acquire statistics during corner-case testing. Serial (digital) data can be extracted to an analog value and graphed to monitor system performance over time, as if it was probed directly. Complete validation faster and gain better insight.

FlexRay eye diagram mask test overlays all the bits on FlexRay signal in an eye diagram with user-selected masks. Trigger on a specific Frame ID or range of IDs, or filter one long acquisition specific IDs, and show only those messages in the eye diagram. Supports SI Voting. Key timing parameters like Propagation Delay, Asymmetric Delay, Truncation and Jitter help you understand how signals propagate along the channel. Use statistics and histicons for deeper insight.

In addition to the capability described above, the standard Eye Diagram capability is also provided. Rapidly display an eye diagram of your packetized low-speed serial data signal without additional setup time. Use eye parameters to quantify system performance and apply a standard or custom mask to identify anomalies. Mask failures can be indicated and can force the scope into Stop mode.
