Automated Physical Layer Conformance
Testing
To perform USB 2.0 signal quality testing based on USB-IF
compliance standards, Keysight offers the DSOX4USBSQ or
DSOX6USBSQ options on InfiniiVision 4000 or 6000 X-Series
oscilloscopes. Figure 10 shows an example of the USB 2.0
real-time eye test. Also included with this option is complete
signal quality test report generation in HTML format. To see the
complete list of supported tests, refer to the DSOX4USBSQ/
DSOX6USBSQ signal quality test option data sheet listed at the
ended of this document.
To perform physical layer conformance testing on the differential
FlexRay bus, Keysight provides a PC-based software package
that you can download from Keysight’s website at no additional
charge. If the InfiniiVision X-Series scope is licensed with the
FlexRay, mask test, and segmented memory, you can perform
automated physical layer tests at either receiver input or

transmitter output test points. Figure 10 shows an example of the
generated report from a signal integrity voting test on a 10-Mbs
isolated “1” pulse. The test report includes comprehensive pass/
fail and margin analysis based on published specifications.
Refer to the tables in the Specifications/Characteristics section
of this document on page 17 to see the entire list of 33 available
FlexRay tests that can be selected and performed using the
FlexRay physical layer conformance test software package.
